i dun think all thos games can be played on a coll computer
it wont support soo much
i think ur good options are quake 3 ( my personal fav. ) , counter strike , ut 2003 , and need for speed high stakes / porsche unleashed ...
games after these require a helluva lotta processin power
u might just spoil the game play for everyone
besides these are the all time hits ... everyone loves them
i suggest one FPS and one racing game
most probably CS and need for speed high stakes should be very good options ...
CS has definitely more players than quake 3 to my dismay
while i was in coll i organised the game fest for 2 yrs ...
1st yr quake 3 and nfs
2nd yr CS and nfs
