I'm out of retirement and I want to know how to play fighting games again;

Will someone teach me how to play 3rd strike, MvC2, GG Slash, KOF, DOA, VF?

Also has anyone ever tried converting a 360 controller to a personal joystick. I'm willing to pay.

With regards to controller issue, stickman .Ix can help yah.

Now as to teaching, I believe you still have the skills.
Just check out the arcades again.
