I'm in the planning stages for my game project and am trying to choose an engine. My choices have been narrowed down to Ogre3D, Irrlicht, and Crystal Space. I'd like to know from you insiders whether Crystal Space meets certain requirements I have. In particular, I need to know if CS fits the bill for this one:

Persistent, Perpetual World - The main game world generally does not have load times when traveling, as the graphics are generated seamlessly. Think MMORPG, though this project is not an MMO.

I'm creating a single-player sandbox RPG that mimics the interface and general feel of an MMORPG, and I'd like to have full worlds that require no obvious loading beyond the initial startup one. Can CS do this easily?
