Save often. Characters will become unselectable or go invisible every few missions. Some of the missions can be tedious, but most are pretty fun. Class balance is all over the place. Some of them are amazing, others you'll brick your characters picking. The game throws enough people at you that you can easily make up for it and run good classes. The interface is far from intuitive and has almost no tutorial, they seem to assume that you've played FE. If you have, you'll find this a simpler version of it. Definitely worth the pickup if you find a deep sale or get it from free off Twitch Prime.
