I use it since early EA.
It is a quite nice product. You can do a lot without ever touching C++, as the scripting interface of TGB is far better than the one of TGE (where much stuff still needs to be done C++ wise).
Currently, the openbeta of TorqueX (or currently only TGBX) is going on and working with C# and TGB is even nicer than doing all the scripting stuff etc etc.
For those freaks using XNA or thinking of X360 it opens up the same paths as XNA to get games onto X360 (TX uses XNA)
