Apart from Super Smash Bros Melee, I was never really into fighting games, except recently. I could never figure out the combos.
I played Tekken... 5 I think, a fair amount but to be honest I either mashed one, or all the buttons.
I also own Mortal Kombat deception, which I played quite a lot. I did start to learn combos there, but I never got far in it.
I am really looking forward to MLP:Fighting is magic, though!
