Ok, i had it for 2 weeks and spent around 15 hours on it. It sucks... I wanted it to be good but the following things make it suck
-running is difficult to pull off, the non responsive controls are a real let down
-cant do max supers cause the buttons
-really nothing new, and the new character is boring.
The only good points are the graphics and the ability to play kof on the go. I recomend SnkvsCapcom over this, that was and still is the best hand held fighter.
you might want to check it out before buying, just be warned, some people think pretty highly of it.....
