Great Game but…
The ui for diplomacy is very bad and confusing. If you accidentally choose a trade option you can’t change it unless you back out of the trade screen. Enemy countries are too bland colours to the point where if there are many countries they can’t be told apart. What could help is if you clicked the nation it highlighted all borders of its land in black and a pop would show it’s name and if they are ally, neutral or enemy instead of using the same diplomacy screen for everything.
