Well speaking of the workdlow, the only 2 things that really annoy me of Gamestudio 3D and those have to do with the editors:

1. You can't color your texts in SED (except for 'comment line') to tidy your script.

2. Mapping in WED is annoying (the camera feels to restricted, shooting out with mouse cursor and moving something else than planned etc.).

But I recently noticed that they are community editors to somewhat replace SED and WED, so these problems are probably solved than too (I hope ).
Also is GED worth looking into?
