zalasur, I've been looking around with the Dwarf Fortress Adventure Mode beta last night. Right now it's fun to derp around in but it's missing a few key features (like you can't craft your own food and there's no trading system).
I will kick of a new fort in the new world because there were some additions to fort mode as well. I generated a crazy world with tons of healthy dwarven civs. I saved that seed because there are some fun possibilities in there. 😉
