Sounds a lot like a graphical version of Dwarf Fortress, without a lot of the complexity.
[EDIT] Before anyone jumps in, I do know about towns etc. but in terms of gameplay depth they are all DF Lite.
[EDIT #2] Totally alien to most people under 30 :)
I am 21 and the game interface is not alien to me!
I don't really know what they're thinking. Sure they have graphics, but that's about it.
