Bout 93 We were using just keyboard and playing Shareware doom on our 486's and having a ball. One day I was on campus using a mouse AND keyboard doing 4 player and he was just MOPPING the floor with these other guys over and over. I went home and immediately started training myself to use the mouse with keyboard and my K/D ratio improved once I got used to it. Jump ahead a few years or maybe a decade and I was playing facing worlds (unreal Tourny, think we called it 2 towers at the time)) with my homies and i'm just killing them. I didnt notice but they got sick of losing and they all joined 1 team vs me, 4 on 1 and I was just beating the snot out of them. They never really adapted to M/K combo very well for some reason.
Old man now, ache's and pains everywhere, still got my caffeinated twitch reflexes though so I got that going for me and can play the hell out of 7d2D.
