I don't really see some name changes and cosmetic alterations to a race as serious impediments - they can be reversed easily enough without any systemic effects, if it's felt to be necessary.I dunno 'bout "better," but the old-school PS model was perfectly possible in 4e, if you were willing to whip up a lot of your own details for things and maybe overlook some of the core 4e assumptions (like what tieflings and eladrin were). You're exactly right in that the PS concept of "center of all" meant that any arrangement of reality is ultimately subjective. But 4e's other fiction changes could wreak some havoc.
As to the overall cosmic conflicts in 4E - I think they make more sense with the Planescape fiction, not less (though, note, that is just a persoanl view - I'm not claiming any absolute superiority here).
The "better" I meant is purely a marginal thing, due to the fact that the World Axis has several of the Great Wheel "planes" as different "realms" or "domains" in the same plane of existence. This makes things like the rivers that flow through several "planes" and things like Yggdrasil marginally easier to visualise/justify. It's not really a big deal - quite evidently running Planescape is perfectly feasible (and better than feasible) in the old cosmology - but I think it brings marginal benefits due to the basic set-up being closer to what might be visualised if one thinks of "divine realms joined by rivers or trees".I just looked over the thread, and granted I understand if you and Balesir prefer the 4e mechanics but... maybe I'm missing something because I'm not seeing how 4e's World Axis does PS "better" than the Wheel... could you or [MENTION=27160]Balesir[/MENTION] elaborate... or is this meant to be a subjective "better"?
I also think of the stories and art in the PS material of planeswalkers leaping from the "edge" of one plane onto another - a concept which really doesn't make much sense if the "realms" involved are not actually adjacent places on the same plane but separate planes of existence. This suggests "lore" to me whereby the fact that there are portals from one Astral Domain to another has misled some folk to interpret them as "separate planes" when in fact they are different "Domains" on the same plane - the Astral Sea.
No reason you can't come up with reasons why it still works as separate planes, though. The "edges" might actually be places where there are "crossings" where the "fabric" between the planes is weak so that "leaping", if you time it right, will cause you to switch planes. As I say, PS was designed for the Great Wheel, so it obviously will work with it perfectly well.
