An Idea For Riot

What I want to suggest isn't to improve the current game, or add a champion, but rather a way to allow people to explore the world of Runeterra in a better way.

I think I've suggested this before with Skyrim, but this time I want to suggest it for Minecraft, too. Since Curse has a partnership with both Riot Games (I think) and Feed the Beast (the main organization for minecraft modding for those who aren't in the know), they could help facilitate the creation of a mod that allows you to basically go to Runeterra and explore it, while interacting with the various champions and cultures in greater detail. They can't make money from it, certainly, but a mod for a game as popular as Minecraft would generate potential new players and provide a new way to express the lore for longtime fans. There was a League mod a long time ago but the person abandoned it before ever getting really anything done. So what do ya all think? What kinda things would make a League mod fun?
