I completely agree with that – there shouldn't be anything really keeping you from porting cosmologies across editions. (Is there even any real reason you can't just bring over the Lawful-Chaotic-Good-Evil axis right over to 4e if you wanted? I've always thought alignments were one of the more disposable/ changeable aspects of any D&D version.)In 1e the Great Wheel was an example cosmology. I take 4e's cosmology to be an example. I didn't always use the Great Wheel when running 1e through 3e; I wouldn't feel constrained by the 4e cosmology if I wanted to run 4e.
thecasualoblivion said:The problem with the Great Wheel is that it is a metaphysical thing that is made to be read and thought about, but the too many of the places it describes really aren't interesting places to go. 4E's cosmology is designed around making the planes destinations that are interesting to actually go to. What use are the planes if it isn't interesting to go there?
I know for my group the problem with the inhospitable planes in the Great Wheel was that once you did gain the spells, magical items or whatever to travel there. You have essentially neutered whatever that plane was about, made it dangerous, etc. by eliminating in one swift blow its only world-to-PC engaging element.

That's something I'm also against with 4e, especially when you consider how easily accessible all those spells that made planes survivable for a party are now, with all such spells easily being rituals. All it requires is a stop in Sigil or some other planar metropolis to pick up a ritual scroll or learn one, it doesn't take that much for a party to survive a plane of burning death anymore.Contrariwise, I find the Great Wheel loaded with interesting places to go. Fantastic places. But 4e seems rather pedestrian to me by way of comparison due to the nixing of the inhospitable planes. Making all the planes "PC ready" is a tremendous fourth-wall breaker for me.
