Hardcore “competitive” RTS (StarCraft/Age of Empires) can’t since it’s not competitive enough if you can’t hit a meaningful 300+ actions per minute, which is impossible without hotkeys. Even IF they could, I am skeptical you’d get converts. Even IF all of them converted, hardcore RTS is not thriving right now. You’d have to create the perfect game and you’d be rewarded with less players than a Minecraft clone.
