I glanced up and down the hallway. My virtual surroundings looked almost (but not quite) real. Everything inside the OASIS was beautifully rendered in three dimensions. Unless you pulled focus and stopped to examine your surroundings more closely, it was easy to forget that everything you were seeing was computer-generated. And that was with my crappy school-issued OASIS console. I’d heard that if you accessed the simulation with a new state-of-the-art immersion rig, it was almost impossible to tell the OASIS from reality.
