I have Disgaea 4 and I played.... a bit of it... Only got as far as beating up the Warden... Yeah...
But I'll get back to it.... one of these days!
Definitely going down and picking up the new Soul Calibur when it comes out. Hopefully it's like 2 and 3 and has plenty of extra stuff to unlock that isn't stupid (glares at 4). I love Tekken, Soul Cal, MvC2 & 3, King of Fighters (although I kinda suck at it), Guilty Gear (also suck at), Dark Stalkers (please make a new one) and the new Mortal Kombat. Smash Bros is always loved, too, but this 3DS is the first Nintendo console I've had since GameCube and Game Boy Color. I did play and beat the resent one on my roommate's Wii back in College, though.
I don't know if I'll pick up Diablo 3, or not. I never got around to playing 1 or 2, but it does seem like something I'd enjoy. Only problem is my laptop has some funny ideas about what Internet means and even when I have a wired connection, bad stuff happens. I'll have to see how nasty the "DRM" is before I pull the trigger on that purchase.
Edit (I guess): Let's see. Um... well games I actually play on my 3DS are Pokemon Rumble Blast, Resident Evil: Mercenaries, and that DOA game when it first came out. Mostly played some DS games when I first got it, but I don't remember which ones. I also got Cave Story 3D and SMT: Devil Survivor: Overclocked waiting to be stuck in there.
I am not a reasonable man.
