Fe13's good: there are a few let downs though.
Lack of:
Diversity in level objective,
Continuitity in the plot,
Light magic,
Early-Mid game longbows,
Rescue!?! (Pairing up's OP).
All of these things put it bellow FE7 in my books. That's not including how broken the game is, with easy Nos-tanking and the like. It's in my top 3 though! (Right after FE9).
Edit: Also no Lucius. =[ Without him there making things more epic, than both sugar and honey in my tea, the game feels like an injection of flat vimto.
