Game limits and the age concept

[Steph]

My new mod is underway.

I already have added the units (I now have 140 units, and will probably add a few more when I found the graphics).
I'm currently working on the tech, and have listed 250 of them.

My question is : does somebody know if there is a limit to the number of units / techs / Improvements / Wonders in the game?

Second question : how do the ages work?
What is the effect of associating a tech with an age? What files should be modified to add an age?
What is the mechanism between a change from one age to an other, and what are the effects of this change?

I hope this new mod would not be playable only by people with the latest, highest-powered computers.

Keep us posted about your project.

I don't know, my computer is a PIII 500 with 256 Mo. I will let you know the result when I palytest it. But before I do this, I would like to know if I have to reduce the techs number for instance before I start : if the limite is, say 128, trying to add 250 techs is not a good idea.

There's one limitation though : my mod is for the French version of the game. I don't know if it will be compatible with the English one. I know that the WW2 scenario for instance doesn't work with the French version
