I'm going with Soul Calibur 4

Definitely Smash Bros Brawl!

I thought Soul Calibur 4 was much worse than 3 and 2.
But it's still the best fighter I've played this gen. So yeh, Soul Calibur 4.

Currently its Street Fighter 4 (tho im sure Super SF4 is better but i dont have it yet)

Forgot about that. Super Smash Brawl definitely!

Fighting games this gen sucked, IMO.

The best ones I played this gen are:-
- Super Smash Bros. Brawl
- SoulCalibur IV (the series is getting worse with each installment).
- Dead or Alive 4
- Tekken: Dark Resurrection

Those are the only ones I would call good/great games.
I still haven't played BlazBlue: Calamity Trigger. Hopefully, it is as good as they say.

1 - Brawl - it's too massive fun.

2 - Tatsunoko Vs Capcom - a very nice surprise, dethroned my dearest street fighter IV from the second post for it's creativity and amazing, amazing fighters.

3 - Street Fighter IV - Just perfect too. I feel like playing Street Fighter II all over again. It lost some points for lack of wild creative fighters - where's the new Blanka? The next Dhalsim?, but maybe Hakram will fix that once it arrives at my home!

But three amazing games! So happy with fighters this gen!!

I've only played 3 fighters so far, Virtua Fighter 5, Super Smash Brothers, and Street Fighter Turbo HD. Street Fighter HD is the only fighter I have enjoyed so far this gen!

tatsunko vs, capcom

second ssbb

It's hands down Tekken 6 for me

The diverse character/fighting style selection and deep learning curve is win, can't wait for Tekken 7 which they might tease at E3 (hopefully)
