Ill have to do some more reading. I saw one video where a developer commented that a group of people getting together to all fight 1 big boss wasnt very heroic, and they were more interested in harrowing battles against insurmountable odds.

I wonder how that will play out if they dont have traditional "bosses." If the combat is fun (dont know either way obviously), the idea of dropping into a planet and being surrounded by a ridiculous horde of robots trying to kill me or something like that sounds like it could be amusing.
