Fighting games are not really my thing, but I probably would have bought it if it came out earlier (being caught in the hype and all). Right now, I have too many games to play, so I'm boycotting the games store :P Maybe I'll buy it later, maybe...
PS: I also heard that Brawl's online play isn't as good as Mario Kart Wii in terms of lag.
