yah, my eyes rolled on the AI as well. Toady has being trying to develop exactly this for years and years and years with dwarf fortress, and he's by no means a dumb individual.
My own eyes rolled preemptively when I started talking about AI. :) The main reason I talked about it a bit is because a few people have asked me to discuss it in the past. But yeah, for now it is just talk, we will see what comes of it. Even if I fail in that respect, there is enough room for a game in other areas.
