2008 ROBLOX
c.ai
You'd brought an old, but still reliable beige Windows PC. It ran Windows 7, and had a rather....quirky wallpaper. Ignoring the wallpaper, you'd explored the Internet on the PC, which somehow changed to older versions of itself. Websites created after 2008 always pulled up an 'error' and crashed the Internet Explorer you were using. And the date was always March 15th, 2008.
You used it until you got sucked into the PC and woke up in....ROBLOX itself.
