Riot is thinking about input/output randomness in League of Legends

For the past five years or so, I’ve been talking about the input/output randomness concepts, and why they’re so important for game design. While I wasn’t the one who coined the terms—that honor goes to the great fellows at the Ludology Podcast—some Googling around shows that no one has talked about the concepts, or developed them, nearly as much as I have.

In short, talking about randomness, especially in these terms, is kind of my thing.

Here’s a quick list of some of the more notable times that I spoke in depth about this subject:

Beyond that, you can (and should) read my books, listen to my podcast and watch the complete 3 Minute Game Design on YouTube.

Between that, and the fact that I recently praised League of Legends and its developer, Riot, for some of the radical things they’ve been doing to their game, you can imagine how pleased I was to see that a Riot designer, Greg Street, made a video talking about input and output randomness in League.

I want to do three things with this article. First, I want to signal to the Riot devs that I would be more than happy to help them out with this project of making the game more input-randomnessy and less output-randomnessy. Let’s chat!

Second, I will talk about the current state of randomness in the game. And finally, I will talk about a few of my recommendations going forward.

The Gist

You should check the links above for more detail, but the very short and rough explanation of input/output randomness is that they are describing the distance between new random information and the user’s ability to react.

Input randomness is stuff like the Tetris “Next” box, or a randomized map—stuff where the user has time to see what the random information is and make decisions based on it. Fog of war is also often used as a mechanism for input randomness: you see stuff usually a turn or two before it can threaten you.

Output randomness is stuff like “roll to hit” in RPGs or games like X-Com. You decide to attack a thing, and then there is random information which comes into the game and determines whether that hit connects or not. In this case, you have zero time to “respond” to the new random information. The course of the game has now been altered by pure randomness, unfiltered by your decision-making.

A quick note is that actually, input and output randomness exist on a spectrum. Randomness which is really close to the user but still technically is input randomness(imagine 1-tile-radius fog of war) may actually be so close as to function similar to output randomness. For more on this, read my article on the Information Horizon.

One more note: as Mr. Street said in the video, output randomness is bad for strategy games. (Actually, he wasn’t that strong with the language, but that is definitely my view.) You also don’t want zero randomness in games. What you want is a carefully placed information horizon.

Randomness in League

There are a number of sources of randomness in League already, but what’s exciting is what they’ve been adding, so let’s talk about that first.

One of the big ones, that they’re talking about in the video, is the new Dragons (or I guess they’re calling them Drakes? I’m going to call them dragons) system. Every game, there is a random elemental dragon. Killing each dragon gives your team a different kind of buff—something like, Air dragons make you move faster, fire dragons make you deal more damage, Earth make you destroy towers faster, and so on. After one of these dragons is killed, a new random one will spawn.

But here’s the cool thing, and when I saw it, I was impressed, because it’s exactly what you should do. The dragon takes awhile to respawn. But on the dragon’s death, the next dragon is selected and a big bright symbol is painted on the dragon’s lair wall for everyone to see. This is a great example of input randomness. Both teams know exactly what random dragon is going to spawn there, and decisions can be made around that.

This system is a really great start. There should be a lot more of this on the League of Legends map (which I guess they call “Summoner’s Rift”? I’m going to call it “the League of Legends map”).

My Suggestions

Category #1: Increasing input randomness. I believe that by making the League of Legends map more dynamic and more different each game, Riot can worry less about perpetually adding content to the system and the sort of “patching just for the sake of keeping things fresh” idea that they arguably do sometimes.

  1. Randomized geometry. Why is the map geometry—the pattern of the walls and everything—the same exact every match? Is this geometry sacred? Remove this brush, put a pillar here, change the shape of this wall. You can definitely design the parameters in such a way that it’s always fair for every character, yet slightly different every game. If you’re really worried about it causing balance problems, maybe have it change randomly at 10 minutes and at 20 minutes, or something.
  2. Randomize all jungle monsters. Having a fixed jungle means having a fixed jungle route. Instead why not have there be a few more jungle monsters, but what they are and where they are is randomized somewhat. That way you can have a more dynamic and less “memorized Starcraft build-order” automatic pathing to the jungling. Make it mirrored, so it’s fair.
  3. Random plants. I love the new “plants” system, and maybe it’s just the beginning. But why not randomize the positions and the types for these plants? Make it mirrored, so it’s fair.
  4. Push the dragons further. Right now the buffs are cool, but maybe instead of just the four elements, it’s four different kinds of monsters as well. So you could have an Earth Wizard who does lots of magic damage, or a Fire Ogre who has shitloads of health. Maybe Ogres, when killed, change the terrain somewhere else or spawn plants somewhere.
  5. Random (mirrored) cannon minions, and more? I like the idea of there being some more variance in the minion-stream itself. What if randomly, every 5-7 waves or so, a super minion spawned on one of each team’s lanes (probably, it can’t be the same lane). There could be a little map alert telling both teams about this. I spent like two minutes thinking of this idea, I don’t know—but the point is, I do think there’s a lot more that could be done with minions than is being done here.

Category #2: Removals of existing output randomness. These aren’t quite as important in my view, and they’re also less likely to be taken up by Riot for a number of reasons. But ideally, I’d love these to be changed.

  1. Remove Random Critical Hits. This is totally unnecessary for this game. It’s totally a vestigial D&D thing and all it does is unnecessarily loosen up a system which already is very loose. I’m actually surprised that high level players don’t complain about this, because a lucky crit at the wrong time can completely change the course of a match.
  2. Reduce execution across the board. This one is hard, and I don’t expect Riot to act on it for that reason. But, in an ideal world, we should be making the game be less about crazy reaction speed in team fights, and more about strategy. Removing skillshots and having them be target-based is one suggestion here. Getting rid of “burst” (massive amounts of damage in a tiny window of time) as a concept would be a much wider scope change that would really benefit the game. That would mean questioning the roles of burst-mages and assassins, which is a huge job, but personally I think it would be worth it. Because, as I’ve written about before, execution is a form of randomness, and this becomes more and more the case the faster players are asked to execute.

(On a slightly related topic, here are some more League patch notes that I’d love to see.)

Anyway, those ideas are mostly off-the-cuff (but not getting rid of random crits. That seriously needs to go), but the point is just to demonstrate some ways that Riot’s designers—and designers in general—can use the input/output randomness theory in practice to create a better experience. Using input randomness in this way, you can get the “variety” that is so sought after using extremely costly (both in terms of production costs and accessibility costs) asymmetry content, while also providing players with a fair, balanced competitive experience.

I’m really glad to see someone as high profile using these terms. If you know of anyone else talking about randomness in this way, please let me know in the comments!

Contests Explained

I have described the four essential “forms” of interactive entertainment, based on four distinct values that these four types of play produce. You can get a more in-depth introduction on these forms by reading this, but I’ll quickly break it down here.

First, you start off with a “bare interactive system” – this is an interactive system that has no goal. I call this the toy. Add a goal, and you have a puzzle. Allow for measurement, and you have a contest. Obfuscate the gamestate (allowing for decision-making) and you have a game.

I would say that the vast majority of people roughly agree with me on the first two forms, toy and puzzle. This makes sense – it makes sense that we would understand these forms first, because they are the simplest. Continue reading

Clockwork Game Design Podcast – Episode 2: Distractions

Episode 2, already!? Yep! I spent essentially all day one day recording both of these episodes, because I wanted to really get the ball rolling. It’s kind of annoying to have just one episode of a podcast, I feel like.

Today’s episode deals with the distractions and other obstacles that have slowed our growth in the path to progress in game design. I think I’ve gotten much more into the groove with this episode – now with fewer “ums” and less housekeeping!

Here’s a few things I said I’d link to in the show notes:

Greg Costikyan’s “I Have No Words & I Must Design”

Game Placebo

Homeopathy, for those who don’t know, is a form of alternative “medicine”.  It involves diluting an active medicinal ingredient into a solution so many times that there ends up being a mathematically near-zero chance of the solution containing even a single molecule of the active ingredient. Yet the United States spent 3.1 billion on homeopathic products in 2007, which can seem pretty strange to someone who understands what it really is.

Now, clearly homeopathy doesn’t “work” in the sense of having actual medicinal effects.  Homeopaths have tried to claim that it does by conjuring all sorts of bizarre theories, one of the most common being that “water has a memory” – it can “remember” the molecules that used to be in it, and somehow that memory has an effect. Whatever – pretty obviously nonsense but that’s not what concerns me here.

Delicious. It’s impossible for anyone to tell the difference between pure sugar pills and homeopathic drugs. That’s because they are the exact same thing.

What does interest me is the fact that homeopathy does work in the sense that people think it works. The placebo effect is very powerful (for some kinds of ailments, anyway), and having a “school of medicine” with practitioners all telling you that this sugar pill will stop your headache may alleviate the pain, since pain is understood to be a highly subjective sense that can be affected by the state of mind of a person.  The simple concept that “you’re being taken care of now, everything will be OK” may bring comfort to that person.  Here’s a really great Derren Brown video showing the great power of placebo.
