Brawl was one of the few decent games to come out of the Wii (The others being maybe one of the Zelda games, or Guitar Hero III, both of which weren't that bad) but I'd have to say if you really wanted a decent games console, In hindsight I'd have gone with either one of the PS3 or Xbox 360. The Wii's ok for things like parties, other than that it's not very ideal. Unless you particularly enjoy abusing the create-your-own Mii channel and churning out such delights as Osama Bin Laden, or Darth Vader or... whoever. Know what I mean?
SBEDIT: I guess what I'm trying to say is, yeah, Brawl was ok, but overall the Wii was awful.
