Tech Tree

English	Deutsch	français	magyar	Türkçe

• Techs To List = Prerequisite technologies that must be open in the region to get the target tech listed on the university.
• Techs For Mats = Additional technologies required for research materials for the target technology
  • If they are not already in the prerequisite chain for that tech.
  • Only the terminal tech in the additional chain is listed.
• Please use the Discussion page for questions/comments/discussions.
