Of the three JM games, I prefer this one. That said, this is a difficult racer at times. While all the original JM tracks return (with a couple technical alterations), many of the new tracks are treacherous and requires more skill than the original game.
The levels themselves offer a nice variety, as well as the unlockable cheats.
Mind you, I played the greatest hits version. Yes, there are some differences between the original and GH (called championship edition). The major difference is that in the original, you could race against 10 opponents, in CE, only 4, but the game ran faster(so they say).
Regardless, this might be an interesting romp. I am underscoring this a bit, but the game and its difficulty isn't for everyone.
