well FWIW I use Ogre3d. Free, crossplatform, exporters for loads of modellers, easy to program (also has optional 'pyOgre' for python). Being just a gfx engine is actually nice as there's no crap to wade through. Just use Raknet or something for networking, 'OgreNewt' for newton bindings (or other physics binding that are about)
Or I'm looking at www.yake.org for a game engine that abstracts ogre and multiple phy libs.
