This seems like a very fun idea. I love idea of having to survive something as I love doing adventurous RPs. All of your ideas seem really fun and good. I have a couple of ideas myself for this and we could find a way to combine these ideas to create a really fun RP.

I would like to be a female who has a strict family so she runs away but is not used to an adventure but while trying to survive she realizes her love for the outdoors but then finds a male but they get into trouble together. We could develop and change that.

I hope that I can join you on this RP!
