I've decided to continue making the 1960s scenario mod using the already existing addon+ mod. Why? Well funny story, on Saturday I downloaded the mod out of curiosity, however I did not expect it to fully wipe all my game progress. This includes the 1960 scenario data. So, I had to remake the entire thing, which took awhile, but I did it. Thankfully, all the custom leaders survived, but things like the custom ideologies I added are gone. Luckly, I have them saved in the scenario mod folder, but I'll have to find a way to reintegrate them into the game.
Heres some screenshots of what the scenario looks like now

 

 

 
 

Hi, I am currently doing a scenario on the first world war
as I am still a beginner to make scenario I helped myself tutorial.
Are you interested?

Me and my friend made a petition, let's show Łukasz how many of us there are! Link below.

Age of Civilizations 2 — a great game that has a huge potential and a motley, large community. How many people have become her loyal fans, who are still waiting for updates on the game, which was released on November 22, 2018 quite raw and with a lot of bugs. Major updates or even simple bugfixes we have not seen, and the developer continues to ignore the messages of players and does not plan to develop his masterpiece. 
 
Łukasz, why did you start making a new game without finishing the old one? You have not yet completed your first, grandiose and large-scale project, updates for which are waiting for all the fans, but at the same time already strive to make a new game? Don't you realize that this very new project will be perceived by the audience with negative for the simple reason that you corny did not finish AOC 2? 
What do we players need? We want to see at least one update that will fix bugs, and in the best case-will introduce global innovations in the game, with new chips and mechanics. 
Łukasz, we, your loyal fans, will remember you as a wonderful developer, and the Creator of a large, and most importantly – a successful project, if you still do what we ask. Believe me, not every one of us wants to see a new project, while the existing one does not meet expectations and prospects. This can always be done later, you have a lot of time for new projects. First you need to bring to the ideal existing. After all, he really deserves it, and it will be better for everyone. Lukas, save AoC II. 
We will be especially happy and grateful if you respond to our spam-action, which we had to arrange to get your attention and response. 
 
Sincerely, dedicated players of your promising project.
