Dwarf Fortress, anyone?

Anyone other than me ever played this? XD If not for the graphics I consider this to be the best game ever made.

It's terribly hard to learn though; you might even need to use some user-made programs just to survive!

However, I never got bored at this, and never ever regretted trying. I still play it when I tire of CB every now and then.

So, anybody? ^^
