From my (very limited) understanding, most large Japaneese developers' "Game Engines" are not designed to be stand-alone products in the same way that Epic's Unreal Engines (or Valve's Source engine) are ... Essentially, they tend to be a collection of large (poorly documented) libraries that (tend to) require a certain familiarity to accomplish anything.
I could be wrong but I suspect that most developers would (probably) be better off taking Panda3d (http://panda3d.org/) or one of the Open Scene Graph projects (http://www.openscenegraph.org/projects/osg http://opensg.vrsource.org/trac) pairing it with ODE (http://www.ode.org/) and making the necessary modifications/enhancements to create their game.
