According to this commercial from Atari, if you have a tough boss to beat in a video game, all you got to do is call a very large person to take them on. It is scientifically proven that only monosyllabic giants have the hand eye coordination necessary to play the most challenging games. This is why Andre the Giant still hold 70% of all video game World Records.
We never has a giant in my group of friends. However, we did have people we called in to take out certain parts of a specific game. This sort of communal playing of video games allowed it to be a group activity. Nothing worse than having to sit for up to an hour while your buddy broke house records on every game.
Sometimes to make it fun we would have elimination rounds on games like Pac-Man. Each of us would take a turn. You play one board and pass the joystick. If you die. You are eliminated and mocked. It was harsh, but it made us into hardened gaming veterans pretty quickly.
