TimeSplitters 2, while an excellent game in its own right, doesn't compare to Goldeneye and Perfect Dark in my view. All fantastic games, I think I just got more enjoyment out of the two N64 games to be honest.
I think that both Goldeneye and Perfect Dark were among the best games for the N64. I tend to prefer Goldeneye but sometimes I have an urge to play PD because I haven't touched the game for years and would love to give it another playthrough.
