League of Legends RPG
The map of Runeterra was shown with the release of the new champion Neeko, this opens so many possibilities for future games. I think creating a game similar to skyrim would be a huge investment considering that there is already a lot of content inside of league that is being unused, such as the in game lore. It doesn't even need to be paid for, it can just be free and have micro transactions just like league haha.
