OK, new version uploaded!
I updated changes from last patches (these that were announced and some of these that weren't).
I will try to keep this updated but it would be easier for us to keep track on changes and react if Gazebo says what he change in units and tech tree. For example all upgrade costs were lowered (which is nice by the way) and few techs were swapped causing some problems. Maybe I've read changelogs uncarefully but I don't think so... Anyway:
Unit tree gets better and nicer but there are still few things to do. As we got rid of most of bugs, it's time to fix "Tech requirements" problem.
1. Tech requirement Tank-ModernArmor, Fighter-JetFighter.
Fix: Swap Internet and Lasers techs. It won't affect other units and in my opinion, it will be more realistic. Internet will require Telecommunication instead of Advanced Ballistic. The only problem is that Globalization won't require Internet which is bad. So I'd swich Globalization and Nuclear Fusion as well. Everything will be enough realistic and millitary tech (Nuclear Fusion) will be on bottom what is good.
Elegant fix for 2 problems at once.
2. Tech requirement Infantry-MechInfantry, Paratrooper-XCOM
Fix: Swap Infantry and Paratrooper in tech tree. This would fix 2 problems at once. Downside is that Infantry should be more common that paratroopers which is now, at athomic teory. I have no better idea how to fix it.
3. Tech requirement Archer-CompositeBowman
Fix: I wouldn't go engineering without trapping but I can imagine situation when this could make sense (rushing for certain buildings, no forests to hunt). Anyway, I don't see elegant solution for this. We could make Mathematics require Military Theory but I don't know if it makes much sense.
