It's funny how the Old Makoto never consider shutting down his own simulation and let it cuck him back in the end. Like, bro, this is the world you created, you're practically god. Why even explain shit to him in the first place instead of just select, delete, upload yourself onto that world, happy end for you?
Even though it's wrong and billions of souls would be in limbo because of that, but hey, nobody would know lol.
