Spin-Off RTS League Game Idea
I think it would be really neat if League could use their different factions to create a sort of RTS spin-off sort of like Civilization or Age of Empires. You could play as the different factions (Demacia, Noxus, Shurima, Shadow Isles, The Void, Bilgewater, Piltover, Zaun, Bandle City, Ionia, Freljord, and wherever else). And your main goal perhaps is to conquer all of Runeterra. It would sure be fun to play as Jinx
from Zaun and blow up every other nation out there to win!
Also on top of this maybe a story mode campaign can play out in the same way Smash Bros. Brawl Subspace Emissary played where you had a core story but different paths to take and timelines to follow. Maybe you start out as Sivir in the Shuriman desert but you have to choose to fight with or against Noxus...or something.
I really wanted to get this idea out there to see what people think and maybe a Rioter will see it and perhaps be able to explore this more as Riot (hopefully) looks to make another game based on their existing characters and lore.
