I personally like TGE better than Crystal Space, but it has been awhile since I used CS. The thing that TGE has going for it is that there is now a shader engine in development that so far doesnt require too much change over. The tools for TGE are getting better and better every month.

 I was curious (I found out about this project today) why this wasnt originally created in TGE, I\'m sure if someone contacted them in the first place you could have figured out something with them
