Hell yes!
And if you were looking for a little more than simply a response to the title of your post then read on!
Gamespace has a wonderful interface and modelling with it is so easy... I love it!
Its animation is capable, and does the job but will be much improved in v2 which will hopefully be out soon.
Its rendering is like a wet slap with a cold fish, but I really doubt thats what you are looking for anyway.
The major advantage of Gamespace is its game related tools. Its got loads of extra features for sprites, texture baking and exports that truespace simply doesnt have. Although the core app maybe much better (truespace 7.5), it does not include some of the neccesities that game developers need. Therefore, do not consider truespace unless you desperately want to render out cutscenes and such, and if you have the money for the gamepak which adds the exports and other features.
Gamespace v2 looks set to be a massive improvement, its core engine is the same as truespace 7.5 and all of the features that were complained about such as uv mapping are likely to be much improved.
