I know what you want.
Mostly I want 3D to walk around in a virtual environment and see things, I can in real life. I especially like nature stuff, trees and grass. But they are really hard to make in real-time 3D. That is why I am learning Crystal Space, to create a beautiful environment for myself and just walk around, and show it to others. Maybe you can learn some of CS and someday we may start something.
Now I am in the depths of CS, I am learning the system part of it, as I want a few things to program (a new canvas especially). Then I would like to model some.
CS already supports really beautiful features, such as height-maps: wonderful terrains can be created with it.
Or a full plugin system: I can implement new mesh types: water, flame, cloth simulation, etc. - specular things. I am still at the beginning, but I am going on well.
But actually, this has ABSOLUTELY NOTHING to do with PlaneShift

I play PS because I like 3D environments, and I have never played any MMORPG before, so...
Your idea is good, but it truly has no relation with PlaneShift.

Search on the web for it, like \"virtual reality 3d environment\" and stuff like that. You will definitely find something.
