you cannot recruit every character nor do all their projects/hangouts, that's by design. the idea is for you to try out multiple runs. we don't get to be completionists here.
that said your background may give you additional resources on certain aspects, but it still won't be enough to do everything in one single save file
arts background, you get a 2nd option later on out of khenbish, themba and wolf. you still have to sacrifice time to recruit robert. that said the leader background will allow to recruit both P and argos, so it's not an exclusive perk
