Actually SSF has a more variety but is very hard to control there is also a walkthrough for it but it really isn't worth it. It has Sonic, Blade, Link, Tails, etc...
Hmm. Super smash flash is not worth it. It's controls are bad, it's hard to play, bad multiplayer, and not so good graphics. Personally, I think the creators should take more time in creating original games in stead of making a version of a game that is not worth it.
