I'm currently working on a few things that, if finished I'll release to the internets for free.
One of the things that keeps stalling/distracting me is the LEVEL OF DETAIL about individual encounter areas.
Example: A 20x30 room with a raised platform at one end. A robot emerges and does a routine and then tries to prevent the party from leaving, defending itself if attacked. Do you think it's necessary to include info about how the room WAS a sales display/demonstration for military gear and the robot demonstrator is now completely crazy because it hasn't sold it's quota in over 500 years?
Simplified question: How much information about what things WERE do you actually want or need?
