My players are sometimes brilliant people. One is my husband and he is pretty much an idea machine. My stepson is young and has been playing with us for about 3 years, so he often takes a more back seat sort of approach then sometimes stuns us with some brilliant insight from left field. The other two players I have confirmed are a married couple we've known for years and years and are good friends of ours. They're whip smart people so this should be a really crazy game because they seem to have taken the whole idea of player freedom behind the sandbox genre and run away with it.
Angie hasn't fleshed out her concept entirely but this is what she has so far. Her character is a 'genetecist'. By that she means someone with little to no scientific or medical training who found a copy of Darwin's Origin of Species and has taken it upon herself to save mankind through a selective breeding program. She wanders the wastes trying to get people to sign up for her 'study', mate with each other, swap people from different settlements to encourage 'strong' genetic traits... I can't wait to see how she tries to convince people to do it.
Jekob has two different ideas and I'm not sure which one he's going to go with. The first one is a born wastelander who after striking out on his own, found a high school kid's backpack with some textbooks and junk and is under the impression that 'High School' is the highest school in the land and he wants to gather the books and materials necessary to re-institute higher learning. The second idea is really wacky and he is supposed to be writing it up for me. I can't really do it justice to describe except to say that it has to do with Knights Hospitaller, mistaken history and Hospitals. When he gives me the write up I'll have to post it. He went into a lot of detail.
My husband decided on playing a Brotherhood of Steel advance scout. A sort of navy seal type guy who has been sent to the region for reasons we haven't determined just yet. He's supposed to be carrying on the non involvement policy of the west coast Brotherhood and looking for whizbang tech to 'secure' for the future of 'humanity', ie the Brotherhood. It's going to be really fun to watch his mission programming break down over time as he is out without the Brotherhood around to tell him what to do all the time. I already decided his ability to communicate with their headquarters will be pretty sporadic. They have access to a single working satellite but because of it's orbit it's not available for use 24 hours a day.
My stepson is making a fairly generic scavenger loner sort of character. He's still thinking about it some maybe he will come up with something a little more interesting.
I didn't give them any restrictions except to say that they needed to not be so loner-ish that it makes it really difficult for me as the game referee to get them together and keep them together. Nothing is worse than some lame loner player who refuses to be motivated or play with the group in order to remain true to their character.
