I believe it was sometime back in 2010, when I discovered the world of ROM Hacks. I don't remember exactly how, but I stumbled upon the Ruby Destiny series, and a download link for the Reign of Legends game took me to PC. My account was initially made just to download the hack, but I eventually returned to PC once I got into ROM hacking myself. So yeah, I discovered PC through ROM Hacking, like a lot of people both before and after me. I eventually did branch out though, and I ended up appreciating other parts of the forum far more than I did ROM Hacking.
