Hi infixo.
This is a great mod and I have some suggestions to make it even better.

Why not fix a certain age?
Basically this mod would have a customizable advanced start in an age and let you stay in that age for the whole game.
Let's say you want to play only in the Industrial age. The game will start then and you can customize how many settlers, units, buildings every civ starts with. Also every civ gets all the techs/civics up to and including of that age. This makes research and irrelevant and tech advantages inexistent so that you don't need to worry about it and you can concentrate on building or fighting. You might also have a certain portion of the map revealed so you know where to build your cities and where neighboring civs are.
