It's the same as the 64 and GC games... but different.
The AI is super cheap with their items too. I've found it easier to sit in second or third and then make your move in the final third of the lap, otherwise you'll get pelted with shells. The 'POW' box sucks too, I really hate it.
Only played multiplayer for about 2 hours yesterday, have unlocked the first 6 cups, multiplayer is a heap of fun, but Im not sure of the 32 tracks will be enough, I was getting sick of a few of the retro tracks after only 2 hours. Hopefully we will be able to download extra retro tracks online, even if they cost $1 or $2 each.
Looking For: Wreckers Saga TPB Collection (with Requiem)
