My friends and I used to hold sleepovers a play games, usually single player. We had roles: Player, guide reader, peanut gallery. And we would just rotate, stepping in if we knew one was better at this than the other. I played Kingdom Hearts with them like that, and Fatal Frame now that I think about it. Dang.
Edit: I love seeing how many people had a similar friend/game set up. Warms my heart. ♥️
We did this with Resident Evil and Silent Hill. One dude was playing, the others watched it like an interactive movie, giving hints and suggestions. It was so great.
We did something similar, it's how we saved all people in Dead Rising. We used to do this for so many single player games, it was such always such a laugh, and we got to finish games I probably wouldn't play by myself.
