When it comes to SRPGs I think this is as good as it gets for the MD and the 16-bit gen, and the game easily outshines its prequel (Warsong) with its improved character customization, balancing, AI and variety.
Langrisser 2 offers a very challenging game (dead characters stay dead), huge battles, cool classes like Summoner and Dragon Knight, a decent story with a lot of humour and twists, and excellent music. Still only playable in English via emulation, but you'll probably want to be able to fast forward after a few battles anyway.
Also: Chou Aniki cameo.
