I grew up playing Quake back in the mid 90s with M&K, so when the PS2 and XBOX came out and multiplayer shooters became really big (Halo, CoD, Medal of Honor...), I had a lot of experience playing these kind of games, but most people in my school had a console. It wasn't even cocky players, every one of them thought that mouse & keyboard was worse.

I never got to show them they were wrong, me and a few friends offered to run a LAN tournament but they never took up the challenge... Now it looks like they post on forums complaining about M&K "cheaters" :).
