I think it is very unreasonable that any country can acquire EoC.Not only is it not historical and tempting almost every other country to get EoC and get the core, when I was playing smaller countries, I always wondered if it would be too easy for me to just go to China and get EoC, which greatly reduced my game experience. Because I lose my motivation to play the game when I have an option to easily get a core of 1100 development. I think the EoC should be limited to, for example, Chinese technology groups and horde in East Asia.
