pretty good tutorials, great explanation of normal/moroha mode.
I'm confident there won't be any ridiculous glitches that affect gameplay. As for controllers to w/e console, if we had it on ps3 there would be the same problem with people who only have an xbox stick so there's really no way to solve that kind of problem unless each person is individually prepared with converters or a dual-modded stick.
Bad news is I have work saturday. The good news is that it's in the morning so I should get off around 4; 3 if I'm lucky and if worst comes to worst I'll just stop buy for some late GG casuals anyway.
