If you really want to play MK9 you should go ahead and do it if you dont mind spending the money to enter.

Are you allowed to play casuals for MK even if you don't enter? that's an option too lol you can play some MK casuals while you wait for ur DOA matches.

Idk. I need to find a main if right now. My choices are Kitana, Raiden, Sektor, Sub-zero, mileeena, scorpion, & jade. Went on to their forums & Raiden & Kitana are the 1s that up there. & Then Sektor. Them 3 are A-listed.

What kind of playstyle do you cater to in that game? that should make it easier to narrow down
