Hi Gilgamesch,
Very good mod you are creating. Very interesting conception.
I tried the last version and would offer for your consideration the following:
- to recommend experienced users to turn off RUINS at the start of game as quick exploration gives very huge advantage to player. AI does not exploring surrounding area fastly. Or to play with modes which increase Barbarians respawn to limit exploration of ruins as early settlers found set near Natural Wonders give gives unfair advandage to player.
- to check Beliefs - descriptions do not match with their effects. I meant beliefs which added to standard ones. For example Kabala does not allow to buy Grate Persons for faith points. Or belief which gives +10

to each city does not affect Culture earning.
- Library requires papirus which is almost impossible to get. Only city on river can build papirus factory which composition is very difficult to meet.
- player who first get beleif of +1

for each forest and tundra tile will get huge advantage in science. Even Immortal difficulty level does not leverage this option got by player. I think it is better to limit such types of advandages within 1 city (capital for example).
- to decrease productivity of

and

as 30 population at the start of Medeval Era seems not realistic. Or to encrease required amount of food for city growth. Plaque is very interesting addition which if enhensed in effect can leverage the rapid growth of population.
Well done! And I hope to try the next version soon.
