The MotoGP games are very good. Pretty realistic and playing the game
with no assists is quite challenging. MotoGP 2 was anyway. The best
bike racing games to date IMO, although I havent played TT Superbikes
which is supposed to be good. MotoGP on Xbox is a seperate game to the
Namco games on the PS2.
PGR 3 is quite good, but it's not sim and not supposed to be.
