I'm not that experienced in SF, but I have played around 2000 matches (I think) in MK9. (Those are from before I picked up DOA). I play those games and it just feels to me like there's barely any depth to them, like DOA has so much more to offer. That's what it feels like to -me-, anyway. Then again, the simpler things are usually the most popular. Take CoD and Halo for example.
