I have yet to see a BlitzMax fully 3D game released yet and I suspect we won't until long after the native 3d module is released.
Well, though you guys wont see it's release, We've been working a paid project since before Max was released, recently moved it over to max, and that uses Ogre. Works well.
People could release their games in Max using 3D if people would put the effort into a fully working usable wrapper. There are a few around.
