The DDT is well under way with a turn-based strategy game that we're pretty excited about. And it uses text on the screen, which works quite well, thanks to Lummox's library.
Yep, Lummox's screen text looks spiffy in this game. And the game itself is shaping up very nicely so far.
I would separate these concepts. Emergent Behavior is cool, and doable in various different systems, but I'm not sure there's anything inherent about FSMs that makes them more emergent than other approaches. From my reading, concepts like "Needs-based AI" are probably more inherently emergent.
At the moment we probably wouldn't have a lot of emergent behavior, but I expect things to evolve/change a lot in a short period, so who knows.
