Minecraft probably. I avoid legitimate horror games (and movies) and the fact that you don’t have saves can get a little stressful when you’re down in a cave, don’t know how to find your way back (and thus probably won’t find your body) and then basically get jumpscared by dangerous enemies or holes in the ground.
Don’t most people have Whatsapp? It’s certainly harder to spy on the content of your messages, it’s just a matter of how much issue you have with giving Meta your metadata.
