We should probably fix all this as well:
-A 40k NS nation being able to support as many planes and navy vessels as a 200k NS nation.
-A 30k NS nation being able to support as many nukes as said 200k NS nation.
-Soldiers just kind of appearing. Why does hiring 150,000 soldiers not have an affect on your population? There can't be that many mercs in the world.
-The world's ability to support 30,000 nations
-Being nuked 5+ times kills everyone in your country.
-There is no limit on how many times you can attack/be attacked.
-There is no limit on how many attacks of any form you can use per day. Especially for air force. (seeing as one CN day /= one RL day, shouldn't we be able to launch far more attacks? And for that matter, to be able to deploy more than once?
-Thousands of nukes being dropped result in a nuclear winter, causing everyone to die.
-You can have as many trade slots as you want
-You cannot build your country on water or move it whenever you want
-You are not limited to 5 of each improvement
- Etc, etc, etc
This is game is fun, but it is not realistic. The fact that nukes would affect other nations IRL is not a reason to include that in this game.
EDIT: Also, this would result in new nations being in bill lock within a couple days. That would kill the game.
