I am in the situation where I am Era 3 Day 8, and have completely researched Era 1, 2, and 3. My Laboratory is at Level 25. I am generating 80 Research Points a day and they are just going in the Bit Bucket. It would be nice to get some benefit from the investment in the Laboratory.
I make the following simple suggestion:
If the following conditions are met:
1. Current Era and all previous Eras are fully researched.
2. Laboratory storage of Research Points is full (At level 25, this is 40 points)
As long as the above conditions are met, newly generated research points that would just be lost are instead awarded as Prestige Points.
Not a complicated solution, and maps the real world concept that one would receive prestige for doing new research.
