I'm having a ton of fun with Fire Emblem: Awakening (AKA my reason for buying a 3DS). It really brings me back to playing FF Tactics between classes on my GBA SP years ago. I've never really been into the FE games, but I might have to look around the Virtual Consoles for a few predecessors.

It does, however, feel like one of those games that I think is more complicated and intricate that it actually is, especially with 2nd generation of characters. I have this feeling that the uniqueness of each unit will fade away when I start a new playthrough. Wouldn't phase me too much though, it's really the perfect game for "play-a-turn during commercials" times.
