Rejuvenation in Seven Nights
So it was a VR BROWSER game? That makes very little sense... It was either a VR game, in which case taking a while to confirm he was not just playing anymore makes sense. Or it was a browser game, in which case it makes NO sense that he would not immediately know it was not just the game anymore. Also, that is a MESSED UP move on the developer's part. Include an achievement/title for doing something that takes 10+ YEARS, and then shut the game down just before it is possible to complete the achievement.
