The more I think about it the more I hate this list, like Far Cry 4 had the worst world of any entry. Literally no Fallout game. Even as a fan of Black Flag the open world wasn't the allure, the sailing was, you can argue it's a big deal for making traversing an open world the most fun part but the world itself wasn't that interesting. I'd even argue it's SLIGHTLY weird to include games like Witcher 3 or Red Dead 2, because those games the open world is designed to immerse you into the rest of the game, it's not the star of the game it's just a tool for the story, arguably most open world games are like this but they did say this list was about the open world itself, while leaving out franchises like Fallout where the world IS the star.
