Dwarf Fortress is one of the coolest games I've ever heard of but is so incredibly evolved i'm somewhat nervous to try it. Like D&D i've gone so long admiring it and not playing it I get lost admiring the complexity and lack of starting it.

That said, one highlight of going to PAX West a handful of years ago was talking with Tarn Adams for a good while about Dwarf Fortress and watching this recent No Clip video reminded me of that PAX. Tarn is a fun developer to listen to and Dwarf Fortress is one of those games that even if you might not have played it it's still an impressive feat and if games are considered art, and I think they are, Dwarf Fortress would rank at the tippy top of that list.
