This game is probably my favorite FE hack, and it serves as both a great demonstration of Thracia mechanics done right and a fantastic game in its own right.

You can be rotating like 25 units by the endgame, and still that’s barely over a THIRD of the total cast size (this game has 73 units, and they’re all pretty unique thanks to personal skills, greater emphasis on base weapon ranks, and a couple of fun gimmicks, like a Ballistician, a Manakete, a Bard who can only use his 5 personal weapons, and a Sniper who’s treated as a flier.)
