I also as a little disappointed in it. Subspace was a fairly poor platformer, and none of the new enemies found therein were interesting at all--for whatever reason, Koopas are just much more interesting than Primids.
I thought the stages were a step down from Melee--where some of the Melee stages had an amazing insanity to them, most of the scrolling stages in Brawl were kind of a pain in the ass (Rainbow Cruise and Pokefloats were so much better than Rumble Falls or Mushroomy Kingdom).
And online for Brawl is awful. Doing random online matches always felt suspiciously like I was playing computer opponents, only it would take 2 minutes to find said computer opponents. I mean, I'll fight as Link, and at least two of my opponents are Link as well (one of them might be Toon Link). Unless a good 70% of all people fight as Link ,something fishy's going on there.
It's a still a blast, and there might be no better local multiplayer experience, but I thought it could be a lot better. Luckily they did a much better job with Kart online play than they did with Brawl.
My consoles and the fates they suffered:
Atari 7800 (Sold), Intellivision (Thrown out), Gameboy (Lost), Super Nintendo (Stolen), Super Nintendo (2nd copy) (Thrown out by mother), Nintendo 64 (Still own), Super Nintendo (3rd copy) (Still own), Wii (Sold)
