The concept of this scenario (moving the start date a little to enhance historicity) got me thinking about the other end. I began to wonder about moving the end forward. A little reading convinced me that 1763, after the 7 Years War, might make a better end date than 1792. As I see it this would have a few playability and historicity advantages:
1. The game cannot simulate the outcome of the 7YW in America - England would have to pick up (from memory) about 20 colonies at once to simulate the Treaty of Paris.
2. By 1763 Prussia was truely a major power, which the game cannot simulate very well.
3. By the last 30 years of the game most players have runaway economies and have or are close to maxing out "research", so why play then?
4. By the late 18th Century that game systems get a little wonky with too many unseigable forts and too much money floating around.
5. The 1520 scenario with a 1763 end date shortens the GC by 19%, meaning you can play 19% more GCs
In summary, I think playing 1520 to 1763 will sharpen the focus of the game and reduce some complaints about the late game. It should make things more challenging for a player versus the AI, and arguably improve historicity. I'll try this when I complete my current GC.
I'd like to hear your thoughts on this.
