Resident Evil: Outbreak File 2- I got it for about £2 and quite a few people give it hassle but I acually had fun with it (it certainly was intresting how Tyrant could wail on you for a solid 5 minutes and not kill you, yet standing around in the starting area for 45 minutes doing nothing will spell your doom).
I've also got to give mention to Turok (the new one that is), depite how bad everyone said it was, it was actually pretty fun from time to time and using he knife against friends is multiplayer is a very easy way to fall out with friends (your dominace over them being apparent until some spoil-sport comes over and fries you with the flamer while you're still carving them like a goose).
Last one, after a friend telling me that it was too hard and boring, I gave Metroid Prime a try (give it a chance to proove itself otherwise) and still think it is by far one of the best FPS games I have ever played (it didn't even need to fall back on the useual combination of boobs and viscera that more recent games do). That and also it was a game that certainly got o peta's nerves...it get better.
