I picked this game up on eBay to add to my list of must play GameCube (GC) games. I'd read mixed opinions of Double Dash online but the consensus seems to be that it is one of the top rated GC games. It must have been back in May, perhaps June when it arrived but I only got around to playing it a week ago. One of the reasons is that I had to get another GC controller first.
Myself and my wife (a huge Mario Kart fan) sat down and played it for a while and were less than impressed. It is probably a bit unfair on the game to judge it after playing Mario Kart Wii so much. Even though there is little difference in the graphical quality, we missed some of the Wii gameplay mechanics. Another problem is that we had played nearly all of the tracks in Double Dash either in Mario Kart Wii or the DS version. I think Nintendo is just being lazy now with having the same tracks in so many Mario Kart games. That isn't a direct criticism of Double Dash but of Nintendo themselves. I'm hoping that when it arrives on the 3DS it will be full of new tracks. I doubt it though.
I haven't played enough of Double Dash to get to know the ins and outs of the main new addition to the game, two characters to a vehicle. It appears to add a little element of strategy to the gameplay and it is nice to see something new in Mario Kart after all these years. With so many games in my growing collection that I've yet to play or games like Zelda: The Wind Waker that I want to return to I won't be promising to play Double Dash much more.
