Disclaimer: I wasn't a huge fan of
Game of Dwarves, or at least not the version I played on release.
The game wasn't very similar to
Dungeon Keeper 2. It's was more like a very "lite"/playground version of games like
Dwarf Fortress. Usually you wouldn't ever lose unless you rushed through the game recklessly.
To me
Game of Dwarves gameplay felt... unfinished. I had bugs with resources disappearing from the resource bar, enemies teleporting all over the place and other
strange or odd events (some of which were "features", others bugs). I liked the sound and art, and decorating the dwarf settlement was fun.
There aren't many (good) Dungeon Keeper-like games around at the moment, though I believe Paradox has a team working on one called
Imperia. For other Dwarf Fortress-like games you've got
Gnomoria and
Towns if you're looking for a challenge and a bit more gameplay depth.
