Mario kart double dash is a very fun multiplayer and has fairly good replay value, but it could have had more tracks.
The controls were very nice and the control stick's sensitivity added a nice touch, some people don't like that but that's probably because they are so used to Mario kart 64's controls. The soundtrack and sound affects weren't to memorable, but they still fit very well with the game. The large roster of characters and combinations will keep you playing for months. And the game play is pretty good for a racing game.
This may not be the best installment in the series but certainly a memorable one.
