I'll give it a spin.
Dwarf Fortress: Where quitting is never really a fit option, on the other hand, drowning in magma... *pulls lever*
Dwarf Fortress: Why is everything covered in X (Blood, vomit, blood & vomit ect)
Dwarf Fortress: Where soon, modding the text files gives you the power to blow up the universe.
Dwarf Fortress: Where you meet the limit of your imagination, moral compass, sanity and CPU processor.
Dwarf Fortress: You pick when you win and you learn, Losing is fun.
Or we could just pick the full quote for the game...Losing is fun!
Either way, it keeps you busy.
