I'm currently in the process of porting over the AI aspect of the Fatal Years mod originally by Athens and then expanded upon by anjou. The scenarios and statistics of units themselves have changed too much to impose the features of Fatal Year upon the Gold version without some serious effort I think, which is why I've exclusively taken a look at the AI side of things and attempted to make it work with Gold. So basically what I am doing is just porting the operative AI part, where units should be moving and so on, while not touching unit production, RGDs and other such things at all. This should also maximize compatibility with future patches and minimize any adjustments that might have to be done.
Basically, the AI scripts in Fatal Years randomize the AI strategy to a certain degree and give it some help in finding proper targets, hopefully giving it some more staying power in the face of a human enemy. A fix I've created for anjou last year that fixes an error that could lead to some crashing in February (?) 1919 is also included and I've run a very quick test and the mod doesn't seem to crash things, at least in the beginning. Still, I don't want to throw something out there that might be crashing or providing an unpleasant experience after all, so if anybody is willing to go through a campaign and tell me how things go, I'll gladly give them the files.
Should it be more or less stable, I'll release it for public consumption, if not, I'll see if I can fix the issues that will arise!
