Not exactly, sure its more fun with other people but there is so much you can do by yourself. Classic Mode, Adventure Mode, Event Match and Online Play in case you need a fix of playing someone else when you can't have people over etc. There is enough for you to enjoy and do in single player.Originally Posted by HyPeRsHoCk
As for me, this game is great. This comes from a guy who didn't like the N64 version, and thought the Gamecube version was alright but would never consider buying it. Brawl just has so much more going for it, it looked so great (and it is). Well worth the money, and its a game that will take you a long time to complete all the way through. Something most of the other fighting titles don't have going for them.
