So I bought this game today on steam and super excited started to play. I have been playing now for two hours and not seen a single human. I have no compass or map so I have NO IDEA where I'm going or what I'm doing. I go building to building to building to find noticing but rags and rotten bananas. Oh I found a Russian coke or some shizit like that. Is there something wrong with my game or is this place just so big that no matter what town I go to the chance of me seeing someone is so small or what's the deal. Please good grief I need help. I wanna enjoy this game.

Thank you all for the good insight! I'm gonna do my best to hang in there. It's always nice when someone helps out the new people! Anymore good info is appreciated!
