Can I just disagree with everyone reccomending Mario KartD? If you want a good Mario Kart game get MK64, or the original SNES one, or the DS iteration. Double Dash was pretty bad though and Nintendo really dropped the ball on it as far as I'm concerned. To begin with, the AI has this annoying tendency to not fight amongst themselves. Unless you do something to prevent it, they'll come in pretty much the same positions everytime, meaning that if you screw up one race even a little bit, there's a good chance you'll lose the entire series. The Karts also have little difference between the classes. The heavy karts accelerate so fast that they catch up to you in a light or medium kart almost immediately off the line, and that's with the starting boost. The inability to look behind your Kart is also a serious downside, not to mention not being able to hold the individual shells behind you, though that bothered me more than it might some. I could go on, but suffice it to say it's the worst entry in the series. I played it a few times after buying it the week it came out and then never wanted to touch it again.
