For a while I had my system language preferences set as en-UK, ja, en-US and every so often I'd get an installation that was in Japanese because there was no UK English version.
I did the exact same thing back when I was first learning web development in 2012. All the PHP tutorials I used were really outdated but since I was new to it I had no way of knowing that.
Thankfully I didn't get the chance to do any damage before I was exposed to modern best practices.
Tell me about it. I started that game a while back and at first I was having fun in the starting area right outside my house but soon I exhausted most of what there was to do there. I decided to try visiting one of the more populated areas but it seemed like the game was designed so that getting there without use of a vehicle would take a ridiculously long time. The game developers wanted me to pay cash for their "public transport" system which was crowded and not all that reliable so soon I was hooked and had spent a even more of my money on a vehicle of my own. As it turns out even that requires "fuel" and "maintenance".
