Hmm I'm actually looking forward to Supspace. Even if it's repetitive it'll be refreshing to do a platformer with smash chars. I got a little of it from Melee (the Zelda stage) and I beg for more : ) co-op within it is a plus.
Some part of the review I didn't really get. It was sorta like a flaw was pointed out but then taken back. Like "Repetition is Brawl's only real crime... After all, how do you revolutionize... a perfect formula? The answer is beyond us"
As far as controller goes I'm surprised SSBB went as far as to include nunchuck+wiimote and wiimote alone. I would've thought it would naturally require either GC or the classic one.
