The earlier games were pretty much pure turn-based fantasy strategy, titus. Closer to the Heroes of Might & Magic series than anything else. Hard, but fun, with lots of long campaigns and single-player scenarios. This one is by a new developer team, but it seems to be following in the footsteps of Disciples I-II. It's out in a cheap bundle now as Disciples II Gold, so if you wanted to try it out it shouldn't cost much.
