Any open-source games similar to Dwarf Fortress and Ultima Ratio Desgum?

[Nekoninja]

I am fascinated with the world building procedures that the Dwarf Fortress and Ultima Raito Desgum have. Is there any other games similar to these games that are open source for research purpose? If there a demo program (open source as well) that I can review the codes for better understanding, I would appreciate it.

P.S. I just remember that Minecraft have world building abilities too.

There aren't many games like that in this world but you should try cataclysm dark days ahead.

Cult was a failed kickstarter similar to these. I believe it is open source somewhere, but I haven't been able to find out where.

I came here to mention Cult

It's open source, and you can even take it and make it your own since it was abandoned permanently. The repository is here (Python): https://bitbucket.org/dmhagar/empyrea-public

The game as it stands consists mostly of a world generator that was built over more than a year, and it's a pretty nice one, at that. (At least the results are nice--not necessarily the code.)

Thank you everyone who replied. I got the game as suggested and will analysis it in the near future. This is what I was able to find after researching for terrain generation. Here is the links:

Hope some one else will benefits from this links.
