Ahh, right. See, this game is a little different as it's not terribly skills-based - the only weapons are paintball guns. It's more oriented towards flying around on hoverboards and interacting with other people than it is towards first-person shootin' or whatnot.
I do agree, it's cheating if you're doing it to gain a competitive advantage over the other players, but in this game, I'd just like to program my character to breakdance, or recite some clever Perl haiku from time to time.
They apparently encourage the use of third-party macros - if you're wondering what game it is, it's called There.
