Eric is given the opportunity to modify/create a simulation-world for himself and others to experience. "He can add magic, rules, and other things to his new simulation-world and he can also change the laws of nature, physics, reality and anything else that he wants" when it comes to his simulation-world until the creation of his simulation-world is "completed with his "modifications, rules, and creations" "continuing after his simulation-world's completion" for "all who or that whenever are at his simulation-world"". He realized that he can connect "the simulation-world he created" to other "simulation-worlds that were created/modified by other people who were given the same opportunity". Immerse into the Simulation-multiverse as Eric and others realize the true nature of the opportunity that they were offered. The Simulation is simply a passtime so that the people don't have "prescious long parts of their lives whereby they're ""not being able to interact with people" and "not having great experiences in their lifetime""". It's like so that a "Hospital patient who wakes up 30 years after first being a Hospital patient" doesn't have to find out that they only have like 15 years left to complete their "bucket list"". They might otherwise feel deprived of the "life experiences that they could have had during those 30 years had they not been "not awake" as a Hospital patient".
