Re: Looking for more stories with a System suddenly being instituted on Earth

There's a few Korean novels that aren't on this site that fit this. Namely Solo Leveling and Infinite Competitive Dungeon Society. The ICDS protagonist was way too dense and just unintelligent for me to enjoy reading the novel so I gave it up. Solo Leveling is a bit better, but it follows the name. There are very few meaningful relationships or character interactions in the entire series. It made it difficult to read but I'm at least still reading it unlike the other one. I think there are a few more Korean ones out there somewhere. 

There's also Gate of Revalation which is a Chinese novel.
