I just saw a video of Arcana Heart 3 for the PS3 and Xbox 360 and the fighting mechanics looked interesting. A sort of Melty Blood-esque fighting game featuring anime girls of every kind. Sounds like a perfect game right?
This game can let you combo easily (even though they're totally n00b combos) which gives you instant satisfaction. I guess you could say this game is mash friendly. Moves are executed via Street Fighter means. Dragon punches, fireballs, flash kicks etc. Super moves are more MvC-ish with a single swipe of a fireball command and pressing multiple attack buttons together.
Though it may look campy, there's a deep fighting game in there somewhere. I just don't know how to pull off those fancy combos and infinites yet and I can't understand a freak of Japanese text so that's not helping. Time to consult good ol Google.
Over all I'm having fun with this old 2D fighter, it looks to be one of those 'easy to pick up, hard to master' kind of games which I like.
