Brett Lowey’s Game Design Commandments

Grab Minos Strategos when you can.

Today, in Episode 36* of the Clockwork Game Design Podcast, I had a great conversation with BrainGoodGamesBrett Lowey. If you don’t already know BrainGoodGames, they make some of the best single-player strategy games out there. All four of Brett’s games—Militia, Axes & Acres, Skyboats, as well as his latest, Minos Strategos—are available on Steam.

But making great games isn’t necessarily enough for me to want to have a conversation with someone. What made me interested was “BrainGoodGames’ Design Commandments” which he posted on his site recently.

The conversation was great and went to a bunch of interesting places. We covered his commandments, of course, but discussed his origins and what he considers to be the successes and failures of his games.

I should mention also that Brett is one of the editors over at gamedesigntheory.org, the new site I recently launched that highlights current game design bloggers and media producers.

Enjoy the episode!

Solvability In Games

What does it mean to say that one game is “more solvable” than another? Is there a relationship between solvability (of any sort) and the point at which players get bored of games?

Solvability

I should start out by making it clear that in game design, we are not usually concerned with true or mathematical solvability. We are not really concerned with the same kind of solvability that AI researchers are concerned with while trying to solve larger and larger Go boards. Continue reading “Solvability In Games”

Arcs in Strategy Games

It is common to hear players talk about “tactics” and “strategy” in games. In this case, the colloquial understanding of these terms happens to be pretty useful, in that it maps well to something that actually goes on in playing strategy games. With that said, it’s worth taking a moment to clarify these terms:

Tactics” usually refers to “short-term decision-making”. Questions like “should I move this character two steps forward, or three steps forward” are questions of tactics. Tactics are micro-level decisions in strategy game play.

Strategy” usually refers to “longer-term decision-making”. Questions like “should I be aggressive early, or be defensive now and attack later on” are longer-scale choices about a game that players make. Strategies are macro-level decisions in strategy game play.

In both cases, we are talking about a grouping of gamestate information over time and how it changes. I refer to this grouping as an “arc”. Continue reading “Arcs in Strategy Games”

CGD Podcast: Episode 34 – Videogames and Game Culture with Tevis Thompson

Writer and critic Tevis Thompson has been on my radar a long time as a rare person who talks about games in a way that is markedly less alienating to me than usual. I recently heard him on the 1099 podcast, which I recommend people check out, and I thought we could have a really good discussion about games and games culture, which that conversation just barely touched upon. And that’s just what we did! In this conversation we talked about big-budget games like The Witcher and The Last Guardian, violence glorification and other toxic politics of games, the hyper-defensive culture surrounding games, and a lot more.

Check out Tevis’s site here. Follow him on Twitter here.

As always, I look forward to hearing what you guys have to say about it in the comments. And if you want to support the show, do so here.

Clockwork Criteria: 6 Guidelines for Ideal Strategy Game Design

What are the criteria that make something a good “Clockwork Game”?

The Clockwork Game Design model is something I have been working on for the last five years or so. It is specifically an effort to figure out how to make the most elegant and effective strategy games possible. There are certainly practical reasons why you might not want a specific game to be a Clockwork game. But to the extent that you want your strategy game to be elegant, you should adopt as many of these principles as possible.

Above: my book

Below is a list of criteria that strategy games should strive for. I am sorting them by how controversial they are. In other words, I am putting the stuff people pretty much agree upon towards the bottom.

These are not ordered by priority. I am making no statements about which of these is more or less important; just that they are all something to strive for. Continue reading “Clockwork Criteria: 6 Guidelines for Ideal Strategy Game Design”

Minimize calculation (in games worth playing)

This is a short follow-up to my article, “Uncapped Look-Ahead and the Information Horizon“, in which I proposed the concept of an information horizon: the distance between the current turn, and the point at which information becomes known to a player (usually, but not always, this means that it has become “public information”).

A simpler way to word it is, “how much time do players have to react to new information?” In the case of rolling a die to hit, you have zero time to respond, so in this case the “information horizon” would be right up in the player’s face. Alternatively, drawing cards to a public market or revealing new terrain via fog of war tends to lend the player a few turns / some time to respond to that new information before it affects the gamestate.

I also discussed the issue in Episode 6 of the 3 Minute Game Design YouTube series.

This concept is important because one of my guidelines for strategy game design is that, as I talk about in the video, if the information horizon is too close, the line of causality and the final outcome quickly starts being disassociated with that of the player’s performance—which is what we’re trying to measure in a strategy game, after all. If the information horizon is too far away, we get a “look-ahead contest” situation where it largely comes down to who calculated (solved) more of the available game state. This is mostly a brief review of things I’ve talked about the above linked articles/videos.

The new thing I want to suggest today is: Assuming a reasonable degree of goal feedback efficiency, we should strive for as little calculation as possible. To phrase it another way, in any game that’s good enough to be worth playing, you should try to minimize the amount of calculation that’s possible.

A reasonable degree of goal feedback efficiency

When we look at a game, “goal feedback efficiency” is a rough approximation that we can make that describes how accurate the end state of the game is with regards to player performance. A game with perfect goal feedback efficiency would give a win to the player who made stronger inputs 100% of the time. A game with good goal feedback efficiency would give a win to the player who made stronger inputs somewhere about 90% of the time.

Every game needs to have a pretty high degree of this, without exception. I’m not sure what the number exactly is, but I would say if it gets much lower than, say, 85-ish%, it starts becoming hard to “trust” a game. If you have less efficiency than that, it becomes hard to defend playing the game.

I would not play a 75% efficiency game. Why? Because a quarter of my matches are sending me false signals about my performance. That might not sound like too big a deal, but it becomes a very big deal when the player has no way of really knowing which matches are the false signals and which aren’t.

The classic answer to this problem is that figuring out which matches to believe and which to chalk up to randomness is part of the skill of the game. First, this strikes me as an attempt to make excuses for what exists, rather than an actual suggestion about what makes for good game design.

But beyond that, I don’t think that this is possible in an unsolved game. It’s hard for me to believe that a person could play a complex game, barely cling to enough understanding to pull off a win, and then also, on top of that, have enough additional systemic understanding to determine that this win was because of random effects and not their own agency. In other words: if you have a balanced game, players will be understanding the system just well enough to win or lose – they will be playing at their maximum capacity. So it’s unreasonable to expect players to be able to also interpret their win/loss as to whether it’s just based on randomness or not.

Ideally, games would have a 95+% efficiency rating, and I actually don’t think that that’s too hard to pull off. It doesn’t mean you can’t have some random variance; it just means that the random variance should be sufficiently input variance so that players can account for it, and to the extent that there is some output variance, they’re small enough in impact and there are enough of them so that they mostly average out. Hundreds of small (+-10%) random damage variance over the course of a match is probably OK, but a couple of critical card-draw failures throughout a match probably isn’t.

This is actually a pretty practical concern. Having a low efficiency rating means it will simply take the player too long to explore your system. In the finite number of hours they’re going to give your game, the amount of “effective depth” (depth the player can access) drops quickly after 95% and then plummets when you go much lower.

Of course, today’s game players who are used to playing stuff like Hearthstone will probably do it anyway, but for game designers who want to potentially someday make something better than Hearthstone, it is critical that we understand and internalize this idea.

 

…As little calculation as possible

So, if you’ve got this roughly 95% efficiency rating (which you should!), then we can ask the question: how much calculation should your game allow for? Or put another way: where should your information horizon be? Quick definitions:

Quickly, a couple of terms: Calculation, for the purposes of this article, means solving. It means literally following logical courses of action to their deterministically guaranteed outcomes. When one does “look-ahead” in games, they are typically doing calculation. Sifting through public, deterministic game states in Connect Four is a great example of calculation.

Analysis, on the other hand, is a word I use for the kind of “thinking” in games that doesn’t fall in that category. When you can’t calculate, you use a looser, heuristic estimation process, and I call that analysis.

So back to my claim:

Assuming a reasonable degree of goal feedback efficiency, we should strive for as little calculation as possible.

Obviously we can create a game with zero calculation – perhaps something like the card game War, or maybe (a single match of) Rock, Paper, Scissors. In these, we’ve brought the information horizon to “right up in your face” – once the other player has played Rock, you can’t do anything about that. But we’ve also destroyed our goal feedback efficiency. Wins have nothing to do with player performance.

The point is, you do need some degree of determinism in games; some “causal line” that goes from the player’s input and stretches out into the system to some extent. But by using input randomness smartly and carefully selecting the position of the information horizon, you can (and should) reduce the calculate-able (solvable) parts of your game down to a reasonable level.

This isn’t just a matter of “balancing” goal feedback efficiency and calculation. It’s much more like, goal feedback efficiency has a floor that it really just can’t go below (95, mayyyybe 90%) no matter what, whereas calculation is much more flexible.

This is because the downside to too much calculation is that the game is a little too solvable, but still totally skill based. In short, it’s a little bit too much like Chess. It’s kind of OK for games to lean into being a little bit Chess-like.

The downside to too little goal-feedback-efficient is that the game becomes indistinguishable from noise, and totally unplayable to anyone who’s alert to this kind of problem. Granted, there are a lot of people who will happily play this kind of game anyway, as so many popular games fall into this category these days, but my writing has never been about “game design guidelines that help you make games people won’t know better than to play”. My game design guidelines are about helping you make good games.

If you build a strong system, with a well-placed information horizon, this new guideline is going to be met somewhat naturally. But it’s another way to test a system you’re already working with and to understand the information horizon concept.
