Game & Wario
Fire Emblem: Awakening
Paper Mario Sticker Star
and now this and other stuff I'm not thinking about/don't know about.
I'm afraid they may be letting Atlus do most of the work on SMT X Fire Emblem (while I like SMT I want that game to have more of a Fire Emblem with SMT character feel to it) and I want an Advance Wars 3DS eventually! I'd rather wait and have them done well though.
Intelligent Systems used to be just the little guys that made Fire Emblem but they've really expanded over the past few years it seems. Hopefully they have more games like FE: Awakening (imo the best of the series or at least one of the best) and less games like Paper Mario Sticker Star (imo a decline in that series).
