I remembered a few years ago when i was playing SF4 on WindowLive, this kid who got beaten 20-0, i kicked him from my room after i am tired playing with noob like him, messaged me, try to "teach" me how to play altho he couldn't win a game, asking me don't do this and that and i should how and how, lol. Some sore losers can never accept beaten badly and try so bad to save their faces.
Btw, fighting game always has a problem, lots of players who couldn't accept losing will come out with their own rules like you can't do throw (especially in old Tekken era), you can't use certain moves, you shouldn't use xxx char because the sore loser has problem to fight it, or you can't do cross-up, etc.
One of my friends always has such friends who set lots of rules to protect themself. But for me, i fuck them directly and ask them stop playing. I am evil, if i know someone hates to get thrown in-game, i will do it till he quit the game or eventually learn the game.
