Voted for 8, but I do really like all the ones I've played. 64 is a classic, played that for hours and hours as a kid with my sister. But I will never forgive how rigged the AI is in that game. Literally, the "no matter how fast you go, you can never be more than 4 seconds ahead of the 2nd place COMM player" just is a huge blight on this game for me. Out of all of them, if I had to choose a game to play right now, it'd be 8. So, 8.
