When playing multiplayer games, we all at some point come across options or paths for victory that are less than ideal. If it’s possible to adjust the rules or patch a game such that the option in question is better or more rewarding, then it might be better for the game. However, sometimes it’s not, and if one has to choose between making a move “too good” or “too bad,” the latter can be the better option for the sake of the overall health of competition. This is what I call the “ryanpeikou dilemma,” after a particular hand in Japanese mahjong.
Ryanpeikou is the older brother of the “iipeikou,” a hand that consists of two identical straights. For example, 123 and 123 both in the same suit would qualify as iipeikou. It’s a fairly common hand in Japanese mahjong, and while it isn’t worth a lot of points the setup for iipeikou is often quite flexible, and so even if you don’t get it you can still be rewarded with something nice.
Ryanpeikou, then, is essentially two “iipeikou”: 123 123 of the same suit with 456 456 of another suit is one example of a ryanpeikou. However, while the two hands are related, ryanpeikou is significantly more difficult to obtain, and in fact in my experience I think I can count on one hand how many times I’ve achieved ryanpeikou. Given the rarity of this hand, it’s understandably worth more (3 han instead of iipeikou’s 1 han), but for the trouble that it’s worth it really is relatively weak. Why go for a ryanpeikou when it’s possible to aim for hands that are easier to achieve and score more in the process?
The issue is that ryanpeikou is a little too weak as a 3 han hand, but would be a little too strong for a 4 han hand. If it’s made too good, and it also has the similar late-game flexibility of iipeikou, then it overshadows many of the other hands around it. Because of the rules of Japanese mahjong, ryanpeikou cannot achieve a satisfying equilibrium of risk vs. reward. At the same time, it would be wrong to get rid of it entirely, because then you wouldn’t be rewarding the player at all.
Buffing in and of itself is seemingly simple enough: all you have to do is make a character or a weapon or spell more powerful. However, the wrong buffs could have unforeseen repercussions, such as over-centralizing the game, and in some cases it might not be possible to deliver the proper buff due to the mechanics or rules of the game itself. So before you ask why a game can’t just make everything powerful, or that it is “always better to buff than to nerf,” keep in mind the ryanpeikou dilemma.
