Depends. I'll probably have an excited friend coming to my house because I'll get Brawl at the release date, but if not, I'll totally own the SSE.
Something odd about me, though, is that I sometimes linger with the box shot, like I do with alot of games I'm hyper about these days. When I get the game, I look at the box for half an hour looking totally happy and I'm like "W00t, I got Brawl, I got Brawl, I have Frikkin' Brawl!! w0000t!!!! Yahooo!!!" My friend went pretty angry at me once. "Play the frikkin' game, already!"
