Looks like a fun idea. Ill be sure to take a look. Are we free to customize nations to a degree? Either alternate history or simply from 2022 onward some crazy things happening? Also, are nukes banned?

You can change a country's history from 2020 onward not before that year.

Nuclear weapons aren't banned, but there will be swift consequences for using them.
