I think, when we all saw Sonic was going to be playable on Brawl, we jump out of happines. But, did his appearance altered the sales on the game? I have to say yes, after all I wanted SSBB badly because Sonic finally appeared on it, and I bought a wii to play it. Also, did you like him? A fast character with only close combat attacks? I did, indeed SuperSonic is the best Final Smash in my opinion.
