What's weird to me about Ryu's victory theme and stage music is that they aren't remixed or updated in any way. They both sound ripped from Street Fighter II. Granted, Super Smash Bros. has included the original music and sound effects from older games, but Sakurai has gone all out before with hiring all those composers to remix songs so I'd expect the same here. I suppose there's nothing stopping remixes from appearing in an upcoming update (in addition to the originals) that actually include Ryu though it's odd that anything would be included in this update. Maybe this is a meta-troll, included only since Sakurai is aware that the update would be data-mined immediately so it was thrown in there to drive everyone crazy with rumors and speculation... SAKURAIIIIIII!!!!!
The more I think about it, the more I want Roy back. From what I understand, he isn't popular among Fire Emblem fans, but in Super Smash Bros., he's been heavily requested to return. I'll buy all the DLC characters and if Nintendo offers stages, I'll buy those too. I accidentally clicked the Mii costumes on the shop. It's like $9 for the costumes in both versions. That was a good laugh.
Anyway, what are everyone's thoughts on Mewtwo? I haven't played him yet. I played against a CPU Mewtwo in both versions then my friend picked him. I rarely used Mewtwo in Melee, but I'm glad he's back all the same.
