Thanks all

However I dont' think I made myself understood
Well,may be there is not a real answer to my question
I dont care if Mr x claims that Torque is better while mr Y supports 3dsg
That's life
I am an hobbyest game programmer , the most important issues for me are :

stability and ease of use.

I am not intersted in super advanced features or super fast rendering which I will never take advantage of
I dont want to design Doom 3 but a complete "low level " game, yes I do
The point is that no other engines receives so harsh critics
I was going to quote some of them but I thought it is not fair
Summing up , they claim ;

"Ok you can easly code a demo or a fragment of game , but if you want to put the pieces togheter , then 3dsg let you down "

To date, I made "fragments of game" only and I must say that 3dsg is the best engine I have ever tried ( out of 4)
However I am scared for the future...
