Dark Wizard is always overlooked.
The playthroughs as the different leaders changed the game greatly.
>Amon the vampire lord campaign is raising an undead horde to conquer the world. Ghosts, Liches, death dragon, etc but weak economy (undead dont pay taxes I guess?)
>ARMER XIII his campaign has a strong economy, can hire a ton of powerful mercenaries and he can lead them in combat personally as he is a powerful unit when he leaves the castle
>crystal the mage leaders an army with powerful magic, runs smaller armies and is weak o nthe frontlines, but can nuke shit and support armies from the castle. She also wears a leotard and has nice legs
>Robin runs a well rounded campaign, she has decent magic, decent as a combat unit herself, good economy, overall balanced campaign. her unique heroes are weak though

Each ruler has two generals which are unique heroes on the battlefield. Most are decent, but one of them is a glitched isekai type cheat hero who can cast all 4 elements, and is physically stronger than anything in the game. You get her to her 4th tier promotion and she is more or less a god of destruction on the battlefield, but up to that point the vampire ruler has tough early and mid-game.

Way more depth and replay value than a shinging force or warsong(langrassier) ttile fro mthe 16 bit era.
