Majin Tensei

Fantastic music, gorgeous sprite art during combat scenes, and a surprisingly robust set of systems that allow for a completely staggering amount of freedom in terms of constructing and implementing your forces. Gets a bit repetitive, especially towards the end, and a bigger focus on ranged combat (ideally including some kind of artillery equivalent) could have gone a long way towards expanding the possible scenarios you have to strategize around. Definitely flawed, but I feel like this really shows how much potential there is in adapting MegaTen's core concepts to a Fire Emblem structure.
