Live the life of a primitive Dowly!

For those not in the know, the developer recently went (at least temporarily) to a donationware model like Dwarf Fortress, definitely worth a play if you haven't yet.

For those who don't even know what Unreal World is, its essentially a Survival roguelike set in Iron Age Scandinavia (with elements of Northern Folklore.) Essentially your thrown into a harsh unforgiving wilderness and your job is to survive.
