I was surprised to read the reasons why they are giving Unity for free
It seems that the cash flow generated by the the Indie version was negligible
In other word a lot of the Unity3d users own the Pro version
Strange, I guess that for 3dgs it is the other way round

Apart form that Unity has still a main issue , in my opinion,
It supports FBX file format only
I have been replied by the moderator tha it is not a problem
"We have many happy clients ",he said," our FBX importer is perfect"
"If you go trough your " external tools " forum ", I said," you see that you have also many sad clients "

If you check the 2.6 bug list you can see that also some FBX
issues have been fixed

I hope tha now the FBX importer really works
On the other hand I am sorry for 3dgs
It can not really compete unless it dramatically improve

I have alwayes been on 3dgs side, but this is the plain truth
