RNG Fighting Game Moves

What do you think of fighting characters that have special moves that change based on RNG (Like Luigi’s missfire, Peaches turnip pull, or anything else you can think of)?

I’m not really a fan, because sometimes the opponent just gets a lucky draw and you lose and oh well. Random stuff basically always does this unless there’s fore-knowledge of when it’s gonna come up ahead of time, which doesn’t completely negate the random effect, but mitigates it somewhat.

There’s a few other fighting game characters that have random effects like that, I can think of Faust, Teddy, and Zappa, from Guilty Gear and Persona 4 Arena. Phoenix Wright too, but the randomness screws him over more than his opponent. Game and Watch has a random effect in smash too, on his judgment hammer.

I mean, I just think all instances of randomness should be replaced by something that is deterministic and can be kept track of relatively easily, but which still looks random to the untrained eye, and has about the same level of frequency in outcome.

Barring that, there’s ways to build more consistent randomized systems, some of which you can see in Project M, some of which you can see in Dota 2.

One thing Project M did with Peach was make her Fsmash totally deterministic, it rotates the 3 possible items each time it’s used. Another thing is making it so Luigi’s next misfire is guaranteed to show up within the next 6 times it’s used, and allowing you to hang onto it. And with Game and Watch, they made it so the judgment hammer cannot repeat the last 2 numbers, and it has a light over it indicating whether the next number is even or odd, so you can stack the odds in your favor

Zappa in Guilty Gear has an ability to summon a ghost, and this is actually dependent on what second the timer is on. Some seconds still produce a random result however.

DotA 2, and a few other games, use what they call a PRNG (Pseudorandom number generator). Technically all games use a PRNG if you want to get really technical, because computers can’t generate random numbers, but that’s beside the point. Basically, when something says it has a certain odds of success, like 25%, instead of it actually having those odds each hit, it starts at a much lower chance of success and that chance increases drastically for each time it doesn’t succeed. This is set up so an ability with a 25% chance will occur roughly 1 in 4 times every time. By doing it this way, they reduce “floods” and “droughts” of a result coming up or failing to come up. People don’t actually have a very good mechanism for understanding random chance, we tend to fixate a little on the odds in the short term, and expect more uniformly distributed results than are actually likely to occur. This system makes it so a 25% chance effect will only very rarely occur twice in a row, and will only very rarely fail to occur after 6 attempts.

My general recommendation is, don’t include random effects if you can avoid it, it usually doesn’t add a lot, even if it’s funny some times. If you feel it’s necessary, find an RNG algorithm that works for you instead of flat % chance.
