The Team Editions are based on the Commercial or Pro Edition, but don't include the license to publish and distribute games. For this, an additional single edition is required. Team Editions for 3 or more seats at a fraction of the normal edition price can be ordered in the online shop or by email to info (at) 3dgamestudio.net. Students can upgrade their team editions to personal full editions at a reduced price.

I don't know if I'm right but here is a piece of information from the Gamestudio page.
