Once the FBX importer is properly implemented for importing a scene, with the option to flag certain objects as models, many of the restrictions for most users will disappear. I've been using 3dgs since A5 was released, and have been using it with Max(which has an exporter in Max2GS-Max2mdl duo). So the art import restrictions were not as bad I guess, but most of the 3dgs users don't have a modeler which can use these tools to import entire scenes of models into WED. I think that the FBX importer will solve this, eventually. Between this, Lite-C, and the new engine, 3dgs is really taking steps in the right direction.

I sometimes think back and laugh at how archaic A5 was compared to A7. It didn't have many essential features, probably the biggest being no per-poly collision.
