Im not sure I want to make a whole new Neolithic Era. What I wanted was to categorize those techs that fits, be placed into one.
Sort of :
Also changed colors on the tech tree. Had fun make a formula that worked
iColor = Info.getEra() * 255 / gc.getNumEraInfos()
(255-iColor*iColor)/2, (iColor*iColor)/(9), (iColor*iColor)
since the colors are not hardcoded.
I added tech diffusion, so weak AI's can catch up, and reduced strengths for later-than-medieval, so combat is still a challenge (It was pretty easy with cavs and rifles to beat knights and arquebussiers before).
I also edited the eagerness for wars for ALL AIs. Lets face it. The way humans win is by conquering land, thereby giving more income, more production etc. AIs had a tendency to stay content by having less land. Not anymore. Better build citywalls and protective units if you want to live to experience Medieval Era. Also the point of "hey! you might be our friend, so we wont attack you" have been adjusted with -20%.
Doesnt sound of much? Before most of AIs had 0% chance of attacking a Friendly AND Pleased civ, even Cautious was a low chance of getting declared upon. Reducing all Pleased and Cautious by 20% makes a whole new dynamic history. Most AI-autoruns result in a Axis/Allies endgame situation with strong Alliances/Vassals. Hopefully this will result in a competitive AI.
Regarding the empty Transhuman Era. TBH I never made it to transhuman era in any game I've played, which makes it a low priority for me atm. Since adding units and buildings will make the game slower at loads, I'm not going to add anything until I'm happy with every era that comes before. I'm hoping the above changes will make it fun to play a challenging Modern Era, but the last game I played was with a friend and we made industrial before the rest of the AIs were beaten. (old settings)
Regarding the corporations, I started to look at Platy's wonders, and want to include tons of them. One of them doubles output of corporations, which might not make them cheaper, but atleast makes them profitable
