My favorite franchise is GTA, so top five would probably consist of Vice City, San Andreas, IV and V. I also thought the first Modern Warfare was a great game. Age of Empires II was great as well. Otherwise I probably played mostly different football games - FIFA and Championship Manager 01/02.
Yeeeeaah! I even prefer it to GoldenEye, it has such fun weapon mechanics. Nothing like filling a hallway with proximity mines, or getting a headshot kill by throwing a grenade at a man's head (I never knew that was possible until I nailed my brother with one of those).
Also, explosives only games are just the greatest.
