I agree. The game really lacks long term incentive to continue play beyond the initial 10-15 years. I have only ever played one game to 1963 in the 7 years (real life) since I got Armageddon when as the Qing where I decided to turn my country into the Middle Kingdom with Asia and the Pacific as my tributaries (puppets). I also managed to max out the manpower pool for the first and only time thus far.A common issue with this game. Once the initial narrative is over, it's dead. Kaiserreich will always have this problem because of the local conflicts.
At the least the base game can whittle the 3 alliances down to one victor through events without too much hassle.
Here is the closest I can get to that, in 1957 just before my invasion of central Asia as the later saves give me ctds when I try to load them,:
