I want a fighting game...

I just had a notalgia attack of arcade mayhem that is the fighting game. Normally I would run out and buy Mortal Kombat but alas, it is not possible (yet).

Can any of suggest a fighting game worth a damn on the pc?

I just got a brand spanking new logitech f 710 and I want to put it through it's paces,

Street Fighter 4 or BlazBlue.

There's also Guilty Gear XX on GOG.com

Super street fighter 4 arcade edition is coming to pc in july! you can buy it on steam now!
