The pricing thing aside, I'd say for the scope of a mobile game, it's pretty dam good. I'd like more content, like characters, game modes and ideally, a feature that takes advantage of using such a huge roster of characters ala a suikoden tactical battle where a unit is made up of multiple characters and the like. It may not be completely faithful to the FE franchise, but it's a good idea for this kind of game. There's a lot of things this could do to encourage play, but meh, it's pretty dam good.
