Runeterra

Wouldnt it be great if Riot at least could bring up the thoughts of creating something like an open world-experience where you could explore Runeterra. I was thinking 'bout maybe doing it a game. But I asume that will take to much time. So wouldnt it be awesome if Riot made something for real about Runeterra. Just imagine an openworld game of Runeterra. Althought it's like all my dreams and aspirations, it will probably not happen... :)
