Thanks for your answer.
I guess i have a lready found my favorite civ.
It's civ 4 in combination with base mod.
More Diplomatic Features, more units, building, techs, leaders, civs(and each one looks different and is unique due to extended leader Traits and civ specific properties.)
But it's not that overwhelming like RAND 2. You can end a Session on epic in 10-20 hours and dont need 80 hours.
