I don't have a 360 let alone the game itself, but my cousin just got it in this weekend, so I visited and we played against each other.
Ryu and Ken are same as always, which is good; Shoryuken and Hadoken are easy to execute, and distant weapons are always killer in a melee fight.
I was actually pretty good with Zangief, they gave him more moves, and many are easy to execute, especially his Pile Driver.
I was able to execute Dhalsim's and Abel's moves rather easily, but I always got pwned when I played them; take that how you will.
I actually pwned as Blanka; traditionally, he's been a lousy character for me.
All the other characters, I've found all their moves, even their traditional moves (aside from Honda's Handslap and Chun-Li's Lightning Kick) difficult to execute.
I don't know about you, but I like using the directional buttons to try and execute the moves, the joystick doesn't sit well with me for fighters; doesn't seem as precise.
Otherwise, I'm definitely going to get this when I get a 360...which will probably be when a lot of games have gone down in price.
Still hugging my PS2! ^_^v
