I'm not sure about NLKS. I've heard bad things about slowdown/performance issues and I don't know that it's my kind of game... isn't it sort of a SRPG + Town simulator?
I'm tempted by DoA for some reason, probably because it's an impressive port... but it's

ing DoA5... I'll have to ask Rai Rai for an opinion on this one.
Katamari though? That's a steal for <$4.
I am now fully digital on Vita after Blazblue CSE was put on plus and I sold my physical copy.
I kind of wish there was a game that I could slide into that slot and just leave it there, but now that I own most of the stuff I want digitally, I don't really know what game to bother with for that. I thought about Dragon's Crown, but I think for the <1gb it is, that's a fine digital purchase...
I wish someone would make an adapter that allowed you to put a SD card into a physical Vita cart and slide that into your card slot for extra storage. Sort of like a Ace Kard, but y'know, without the piracy.
