I'm sure this will end up as a dead end like it has everywhere else I've tried but I'm trying to identify an old game I played in ~2006, it was a demo when I played it so I don't think it had come out long before then, here are the details I remember:
It was a strategy game where during skirmish/multiplayer the only thing you started with was a single powerful hero unit, amongst its abilities was one that allowed you to transform into a base structure and start producing workers and building a base. This ability disabled your character for a long time.
You could choose not to deploy and instead fight a 1-man war against your enemies, after about 3-ish minutes you could regain control of your 'deployed' hero and join in fighting with your army.
The factions were (IIRC) humans, elves and undead.
During skirmish you could kill mobs and visit shrines to power up your hero (indefinitely as I recall) or you could visit neutral villages and barter for their allegiance, at which point they would start spawning units to attack your enemies.
I loved playing it when I had it but can't for the life of me remember what it was called, I thought it was on PlayGreenHouse.com
, but having checked there I must be remembering the wrong website.
It's a long shot I know, but does anyone remember this game and what it was called?
