this game's base roster is very bad. even within its self imposed limiations of three games, some choices are very strange. for how important the weapon triangle is in fire emblem it's not represented very well here, lances are limited to one moveset copied through 3 pegasus knight characters. this could've been alleviated by the original lord characters using a lance and an axe, but for some reason they're just added to the sword unit pile. the story's not good.
what does bring this game up is that it is cool seeing a bunch of fire emblem characters beat up hundreds of enemies, the remixed songs are good, and the dlc does bring some glaring base roster omissions like azura and tharja into the game.
