After checking some other posts in this forums about the games "KOHCTPYKTOP: Engineer of the People" and "Bureau of Steam Engineering", I decided to check who made those cool games. My extremely long and tiresome (google) research led to this site:
http://www.zachtronicsindustries.com/Seriously, check out the games there. They are really wonderful, and I'm sure DF players will like them, mainly because:
1. Many rely heavily on designing stuff with parts and such, such as a steam robot, or a factory, or digging tunnels, etc...
2. They are quite complex (and have a steep learning curve ofcourse
)
3. Some are truly original IMO, as I've never heard of any other game that is quite like them.
4. For the DF players who are into programming or similar logic-oriented passtimes such as puzzle solving, there are games that use a simplified coding language ingame to control certain elements, and there are games that can be really hard puzzles such as the most recent game "KOHCTPYKTOP: Engineer of the People" were you build microchips using semiconductors and such
All in all, fun games to melt your brain in your spare time
Basically, they are all games that encourage creative thinking and tinkering, while being complex enough to keep people interested
EDIT: I just noticed that the community on that site seems to be well aware of Dwarf Fortress, as is apparent in comments about a very dwarfy mining game
