Exactly, the only route that seems simpler is Thomas' route, and even then if you give Charlie a shot once, your chances with them go downhill.
I also didn't understand why I can go to some places, especially in the city since you don't have options to meet the other guys who are presented , as the bar owner and the policeman. I think this may still be in development. I'll just hope the game's dev is actually working on an update. I hope there's more Charlie stuff and some Willie stuff since there's nothing from him by the way.
Anyway, let's hope and wait!
