I like to drink that the people of this world do more than just drink
You sure about that?
the game does not show much of what they do on there free time, all i see them do is fish, drink, gamble, stirp club maybe?, and watch the tv of people killing each other and other things.
like maybe have in one of the settlement have them do painting maybe or making toys on the side for kids in the underrail something to show they do more then that, hell given we see in this have jet skis now they would try to race them, or maybe with the cave hoppers keep them as pets and race them or make them fight each other or given they have fish have them have fish tanks to show off there pet fish.
and come on this world have computers all over so give me a logically reason none of them try to use them to play a game in a safe area like the core city?
