After hearing much hype about it I got to playing Fal from Heaven II mod for Civilization IV.
It's AWESOME(to the point it only could be more awesome by somehow adding giant robots in medieval fantasy)! Some highlights from my current first playtrough:
-My chosen faction doesn't have a specific hero like the other factions do, instead they randomly spawn adventurers that quickly get exp every turn and then can be promoted to any unit I unlocked by paying gold, so after some time I end up with a bunch of "heroic" troops.
-First other player I meet is psycho pyromancer.
-Galadriel elf chick found while exploring the sea.
-Another goody two shoes factions builts a gate that spawns a new civilization consisting of angels, taking over the city in wich they apeared by allying with the faction that allowed their existence. Other good units that die join their side.
-Pyromancer turns against me and sends waves of skeletons! And flaming zombies that explode when killed!
-Ah, I finished researching gunpowder! Eat guns you dark mages!
-A bunch of enemy troops sneak trough my defence forces and advance towards an unprotected city!
-I promote an adventurer I had building exp. He proceeds to single-handedly defeat a dozen enemy troops.
-As casualities builds up the "armagedon counter" builds up, spawning the four horsemen of the apocalypse one by one!
-Super-plague dizimating my population, I'm kinda screwed...
-Hey, wait, my leader can change one of his abilities every X turns! I pick one that increases all my city's health for free!
-As I push into enemy territorry he spends his once-per-game spell that causes meteors to fall on all my cities, but I keep pushing forward!
-Hey, mythril mine found on eneny territorry! Conquer the nearby city and call my troops back to equip them with shiny new weapons!
-Third horsemen of the apocalypse spawns, aparently gets insta-killed right away due to unknown reasons.
-Finally find the enemy capital, protected by several high level firebal-throwing mages...
-I get special medics specific to my factions that allow me to quickly heal from fireball burns.
-Doesn't seem like there's any upgrade to increase their healing abilities, so I just increase their basic combat.
-Final assault on the enemy, damn summoned skeletons keep chump-blocking my elite troops...
-With the skeletons out of the way my medics attack and kills his mages! WITH THEIR BARE FISTS!
-One enemy down, six more to go!
