So I tried out the pad tonight, just one match against the CPU. Definitely a hell of a lot more responsive than the 360...well, that's not a d-pad, I'll just call it the Gimped Analog Stick from now on (Or GAS for short). The one problem I'm having, and this is just how I tried it, is playing it like it's an Arcade Stick, something I'm not accustomed to. Although I was hitting moves more with this d-pad, I still messed up a good number of times. But once I got the rhythm down, I had it, until I lost my groove again.
The Turbo buttons work great though, as is noted by the last achievement I got. And no, it's not from Street Fighter.
