As I understand it, you CAN legally use TGC models from the store in any engine so long as you can manually convert them properly which may take an awful lot of work. From their
Terms of Use:
Quote: "(e) Your right to use Assets in Games.You are hereby granted a personal, non exclusive, non transferable licence to:
i. modify Assets and integrate Assets in "Games" (as defined below) created using FPS Creator, FPS Creator X10, Dark Basic Professional, Dark GDK or in other Games; and
ii. issue copies of such Games (and permit others to issue copies of such Games) to the public:
1. for non-commercial purposes; and
2. (subject to the further terms below) for commercial purposes."
You'd have to get the proper converters and clean-up the models for Unity, but I know it has been discussed quite frequently on the main TGC forums. People recommend Ultimate Unwrap as one tool to assist.
