Minors unrealistically powerful in this game. They should not have same amount of research capacity like majors! There should be another way to give them ability to catch up with majors, here 2 ideas :
- When some technology gets researched by 4-5 countries in the world this technology should cost less , -50% for example
- When trchnologies are researched by 3-5 countries they could start automatically transferred to smaller nations, to neighbours and so on.
It's more realistic and logical that some minor with research abilities like Germany or other major.
