With the release of Savage Species, a lot of outsiders other extraplanar/supernatural creatures will probably get a lot more scrutiny; PCs obviously need a great deal more detail than most NPCs.
So what ecological considerations should be made for various outsiders and elementals. Do they eat? If so, what do they eat? Do they sleep? If so how, and for how long? How old do they get, or are they effectively immortal? For my money, I say that most outsiders and elementals don't need to eat, and sleep is greatly reduced, maybe once a week if at all.
These questions likely change depending on the type of outsider. From 2E Planescape, you have Faces of Evil and Warriors of Heaven describing the celestials and fiends, but it's slightly vague, and does nothing for covering the various elementals, geniefolk, and oddballs like Modrons and Mephits.
Besides the purely physical stuff, alignment can be an issue. Many outsiders have alignment subtypes, which indicates a real link to the forces of that alignment. They are obviously intelligent and have free will, but how far does that free will extend? A djinn, for instance is [Chaotic] and [Good]. He might try to serve Good by doing certain acts, but is he supernaturally constrained from serving evil on accident? This is a big can of worms, so I think I'll narrow the field to those worlds that use the default Greyhawk type cosmology. Different gods would be okay, but keep the basic metaphysical rules the same.
Whaddya guys think?
