Checking up on NIS, something I haven't done for ages, I guess I'll tag on Atelier Meruru to ones I'm getting for sure. I've enjoyed both of the Atelier Arland games so far (Atelier Rorona and Totori), and if they keep up the improvements I'm sure this one will be splendid as well.
There is also Hyper Dimension Neptunia MK2. Even though I really enjoyed the first, I'm not sure on this one. They will need a pretty big change to the battle system, since the other one can get very repetitive, not something that will last for two games.
