For me, it would have to be Timesplitters or Madden 2001.
Ive got Timesplitters and multi player is excellent, but it is frustrating playing people who havent got the game as they take a while just to get used to the controls, let alone get anywhere near your standards.
I hired out Madden 2001 the other day and that is just astounding. Im English, so u wuld think that i wouldnt like american football, but this game is class
btw, does ne1 know a web site that explains how the nfl works?
