For our RV "camping" club the games all seemed to be for sitting around in an air-conditioned clubhouse: Mexican Train, Skip-Bo, RummiCube. Nothing as intellectual as Yahtzee.
But not everybody sat in the clubhouse to play table games. For the rest of us there was a lot of hiking, fishing, storytelling.
When I've been out with pre-teens, our grandchildren or others, there has not been a lot of interest in formalized gaming. More physical activity is involved. Fishing works for a while, if there is some success, but learning or exercising camping crafts (making fires, building things, camp cooking) tend to hold interest better.
