Hmm, let's see. From what I can come up with, I would try:
- BlazBlue Continuum Shift Extend: okay, so this game doesn't actually come out until Feb. 14th, but still. It's a little hard to pick up, just due to the fact that there's a lot of system mechanics to wrap your head around. It's usually the most daunting aspect of trying to pick up BB, and the combos can be a bit on the long side. It's not as fast as MvC3, but it's nowhere near as slow as SFIV. I say if you're interested in it, I would give it a shot. It's a really fun game, and it can be really deep, if you want it to be.
- Arcana Heart 3: this game is only out on PSN, but I'm pretty sure you have a PS3, so it should be all good. This wouldn't necessarily be the first game I would jump to, but if you don't mind the anime aesthetic and all-girl cast, it's a pretty fun game. The combos aren't too hard, homing is a cool combo mechanic, and the Arcana system is really interesting way to customize characters.
- King of Fighters XIII: okay, not gonna lie, this game's execution can be pretty strict. But, to me, KoF takes everything that I don't like about Street Fighter, and fixed it for the better. If you've never played a KoF game before, you might be a bit overwhelmed by the huge selection of characters. But it's really fun, and it basically fits almost, if not all, the criteria of things that you want.
So, in my opinion, try BB or KoF first. Or try Soul Calibur V when it comes out. I don't know a lot about the Soul Calibur series, but a lot of Smash players really dig it, so you never know.
I hope that helps. Let me know if you have any other questions, I don't mind at all. :3
