WHY!!???
I do recall playing Street Fighter II quite a bit in my younger years but I can only assume that I was terrible at it back then as well. Here's how bad I am. Medium settings, I could not get past the third round no matter how hard I tried. It seems that the timing aspects of Street Fighter just aren't within my capability to grasp. In my defense, as I said I'm a DOA player. There are a plethora of moves for each character in that particular fighter and no gimmicky ultra or super moves that try to balance a round out by giving you a one hit kill when you've almost been beaten. I do think this system works for Street Fighter simply because the moves are so difficult to pull off. The button combinations in games like Tekken and DOA have always seemed far more difficult to me however they are a bit more loose to facilitate fluid combat. Street Fighter uses extremely simple combos and focuses on the ability to string them together. Problem is the button combos don't seem to work. I really couldn't string together three or four of the simplest special moves playing as Ryu, let alone nail an ultra or super move when I needed it most.
I suppose if I have the time to sit down and play this for hours on end and learn the techniques I could get good at it.. but I really don't feel like it honestly.
