A turn based strategy game by Strategy First, Disciples allows you to play one of four factions:

The Empire
The "good guys" - focused on life and healing
The Dwarves
RuneLords in the mountain peaks
The Legion of the Damned
Infernal hordes of demons and devils
The Undead Horde
Exactly what they sound like

Resource gathering occurs by owning the terrain on which a resource generator sits. Armies are squads of up to 6 units led by a hero. An interesting game, although the player-cast spells tend to make for stalemates.
