How to mod a limit of specialized tech trading?
So, I always go around trying to collect all the specialized tech through trading, but in the end I find it very unsatisfying to have EVERYONEENDSUPWITHALLTECH. Ruins the point of the specializations.
How can I mod the game to disallow trading a specialization tech if you already have one of the other specializations? And while we're at it, how to disallow trading tech that requires a species ability?
