Sorry, but you absolutely don't need a stick to play this at all. I'm currently sitting at a respectable 1100+ BP and only use the 360 analogue, I'm not amazing, but I'm a good amateur and can hold my own against nearly anyone. If you spend more than a few days before giving up on it you'll come to master your own pad like I have mine. Sticks are only needed for those who want to be totally pro and need that extra 1% (if that).

Fantastic game, it courses through me now. When I'm not playing I am thinking of playing. When I am playing everything else fades out.

Oh, and can we stop spelling it "Hadouken" please? It's Hadoken, and is spelled suchly everywhere in the moves list. Thanks.
