The NDS game is a remake of the first game and was very average. Yeah the support system has been in the series for a long time, but I think having the 3D visuals helps a lot, I get the feeling that Koei Tecmo assisted a lot in that regard. The hub feels very similar to the Attack on Titan 2 game. I think FE is a lot easier to get into than FFT as far as SRPGs go, but it's not shallow by any means.
