I wonder if there's a way to encourage people to play more characters from other countries. Like a type of character you can apply for only as a second/third etc set in a different country than your original, but only requires half activity each month. Basically, something that would encourage people to play characters that are super hard to get cr and activity with, without having to take on the challenge of keeping up with ac in an underpopulated nation/etc so that it will become more populated and thus able to more easily get cr and activity there.

It might need to be crossover/Ocs only, or there could be the option where people can still app the part time characters as full time ones so if someone wants to play them, otherwise would end up either with a challenge app or the person playing the temporary character dropping them and moving on to another.
