So one thing i understand, but dislike in games is that smaller players tend to leave.
It gets scary.
but maybe they could swear vassalage? Giving some of their score and tax to a stronger player.
--it wouldn't be a coalition victory, but they could be indirectly adding to a coalition victory, which i think is interesting.
-- noob friendly, right?
-- more elements to diplomacy and backstabbing
it would also be really nice if their nation name changed! so instead of having ''British Burma" it could be Burma, and then after becoming vassalized or colonised the name would change
