Re: [osg-users] Why no games with OSG?

Hi Maia, maybe the stuff I am working on is interesting for you: http://code.google.com/p/dtentity/ DtEntity is similar to Delta3D in its functionality (it started as a Delta3D module), but it is more lightweight and less intrusive. DtEntity is a game and simulation system for OSG. It has basic
