IwubCheeze: I've never seen a fighting game where you had to rotate the stick 360 degrees but 180 degree rotations could be common (SF2 Turbo had plenty).
I am unsure if the PC version moves lists is exactly the same (I guess I should try to find the game manual), but I think this is for the arcade version of SSF2T:
http://strategywiki.org/wiki/Super_Street_Fighter_II_Turbo/Moves On that list I can see that at least these moves
T. Hawk: Double Typhoon
Zangief: Final Atomic Buster
seem to require one to perform double 360 degree rotations (ie. 720 degrees). So maybe those are the ones I was thinking about. There are also some other moves there requiring e.g. two 180 degree rotations one after another, like Dhalsim's "Yoga Inferno".
If those rotations require also registering the diagonal points, I'd think it is quite hard with a keyboard. E.g. if you were using a WASD setup, I presume you'd have to do in a quick succession something like:
A + AS + S + SD + D + DW + W + WA + A + AS + S + SD + D + DW + W + WA
Punkoinyc: Fighting games are better on consoles. It's just easier to play local multiplayer sitting on couch and looking at big screen TV than crowding around a computer.
I tried playing some Virtua Fighter 4 Evolution or somesuch on PS2 with my wife, but we both got overly bored by it in no time. Then again neither one was an expert in it, I think we were both just pushing the attack button as fast as could, and then see who fell down first.
Maybe I'd find a more interesting adversary online, but then I prefer playing most of my games, including fighting games, alone against the computer. If the real meat of fighting games is playing against other humans (ie. the single-player part is usually crappy and uninteresting on them), then I guess fighting games aren't really a genre for me.
Nowadays playing PC games on TVs is more feasible than years ago, with gaming-capable laptops, long HDMI cables and wireless gamepads. So I guess playing human vs human on the couch is quite feasible with PCs nowadays, but maybe most people are nowadays doing that online, regardless of the extra lag.
