Immersive Eras

Immersive Eras (Version 4. 0) Complete most Techs and Civics in each Era in order to progress to the next. Both the Tech Tree and the Civics Tree have been completely reorganized to maximize immersion. Each Era is unlocked with a key Technology or Civic. (An exception is made in the Tech tree at the Information era because it causes an unusually long load time.) A naval line of techs begins in the Ancient era and ends in the Renaissance era. Land locked civs don't need naval techs until they reach the Industrial era. An air unit line of techs begins in the Modern era and ends in the Information era. Air unit techs can be avoided until the Information era but are still required to complete the Tech tree. Now the AI is forced to research everything in hopes that it will utilize all available units. Research costs have been changed only as needed for balance. This mod is designed to be compatible with all mods that don't make changes to the Tech tree or Civics tree. Have fun! Feedback is appreciated..
