Guitar hero with the plug in guitar. that game is fucking cool. i play it at school alot on the PS2 we have there. but my all time fav is walking off campus to get stoned w/ my teacher, and then me and him team up on Halo 2 and kill all the little kids from the younger classes, and they get all butt hurt and cry, lol. me and him are just hella stoned staring at the screen saying things like "boom headshot", "you got owned noob", "you suck at halo 2 dude" so fun. i modded the PS2, action reply and you can put your own music on, i put some greatful dead, and some jimi hendrix, and pantera songs, etc. its great.

EDIT: im so stoned right now, reading that, haha, im going to smoke again right now and play some doom 1 on my modded xbox, then maybe some contra, some xbox live. my xbox has every game for every system made before N64 (Famicom 64 for UK i think its called?)
