This seems specific to your family. My family would never allow that unless they knew the parents of atleast a few people at the place I was sleeping over.
In North Branch MN there was an old movie theater with the seats taken out and tables setup - The BattleShack. parents would dump kids there and they'd be there for days or weeks just gaming and hanging out at the Denny's in town. My buddy had a workshop addon to their house where the same thing would occur. Summers around us were just a solid LAN Party.
