Finally unlocked all of the characters, and I'm happy that R.O.B. feels better than Brawl.
That said, I'm finally starting to settle on Robin, ZSS, and Bowser Jr., with Lucina, Sonic and Little Mac as likely seconds.
Also digging Palutena, Pit/Dark Pit, and Dr. Mario.
I've played the demo of MKX at Fan Expo here in Toronto. I'm suitably impressed. It's more lenient on inputs than Injustice, but feels faster than MK9 and shares Injustice's special inputs.
Sub-Zero feels very similar to MK9, and his styles mostly play off expansions of his 9 moveset.
Scorpion...
Online gets like that, unfortunately. If you check out FreeStepDodge, the big DOA forum, you'll find no shortage of players who'd rather not mash who could play against you.
Out of curiosity, who's your main?
I'd heard that the old-gen versions were download-only... never mind. I checked, and it's only on Sony consoles and the XB1. Sorry to all the 360 owners.
