SSFIV is still fought on a 2D plane, just with 3D character models. I like this format better than fully 3D fighters like the Soul Caliburs, simply because it makes pulling off complex combos easier and I don't have to worry about my character circling around my opponent instead of doing what I want him/her to do.
And the 360 controller is perfectly serviceable for playing against friends, there's no need to splurge for another controller simply for SSFIV. You just need to not suck at pulling off simple combos like Down-->Right-->Fierce Punch.
And Lynk, if you do want to spend the money on a fightstick, don't get the standard version as they're flimsily constructed and will probably break on you. Spend the extra cash and get a Tournament Edition stick, because they're built better and won't fall apart on you 10 battles in.
