so i am a bit confused with this - is there a 'game' in this 11GB download or is it still just a tech platform for users to build a game upon? Cause in the sandbox mode it seems like the character is just running around in an empty map with nothing to interact with and no real purpose. If we preload some of the user maps, there's a little interaction but it's quite limited. So I am assuming this is simply just an engine and no real game here?
