Love this game too, never played one of Stardock's games before, played quite a lot of turn based strategy though. I like how they melded the combat of Might & Magic with the city building of Civilization, I think it's such a great marriage of genres as well as the excellent customization options for pretty much every aspect of the game.
The only thing I feel is missing is being able to play real fantasy races Orcs/Lizardmen/Undead etc. (I know there is the Stormfront mod, but does that work with Legendary Heroes? Also is it balanced well?).
