So how does the High TL advantage affect the invention rules? In the concept and prototyping phase there are modifiers for inventions above the inventor's TL, not the society's. As I read it, High TL appears to be a background advantage that affects the character's starting gear and skill choices. It would seem rather cheap to also remove a significant penalty in the invention rules.

Are the invention rules assumed to start at any particular TL or at the costs uniform regardless of the inventor's TL? It seems expensive to invent something at lower TL and almost cheap at the higher TL. The charts in the basic set look as if they assume invention is taking place at TL 7/8.

Besides After the End and Mars Attacks, are there any other supplements that address the Gadgeteer advantage and invention rules?

Thanks ahead of time!
