The two-player mode is not terribly interesting, although at least you can now share your consternation about the game with a friend. The time attack offers some more amusement, but not much. Skilled drivers will quickly settle upon hard, however. Only on that level did I have to develop some proficiency with the game's controls and cars in order to win. GT64, which appears to be a feeble effort to replicate the success of Gran Turismo for the N64, falls far short of that.
Replay value is also limited.
