Epic War Age (EWA) - Adapted Mod Collection

What will happen when updates for other mods, which this collection consists of, are released?

It depends on the significance of the update itself. Since almost all mods in EWA have been modified, fixed, and expanded, I will assess whether it is even worth updating.
I have extensive experience creating something similar for Fallout; most often, I would update the mod and re-implement my changes (if required). I release updates as a cumulative patch. You install the distribution (~1.5 GB), and then apply the patch on top of it. The patch's size increases with each update, but it is insignificant compared to the main distribution.
You won't have to keep track of EWA versions on the forum. The launcher checks the relevance of the installed version when launched (it doesn't scan files; the version is written in a txt file, and the same file is on the server; the launcher only compares two lines).

But I might take a break from modding for the next few months; I'm going to be a dad soon :D But I will still have time to read the forums and take notes, at least while I'm at work :D I can even do some minor things :D
