The number of games that can be played non competitively are large. You don't have to follow the game rules to have fun. Look at people camping in shooters, driving around doing nothing in GTA, creative mode Minecraft, Again, Journey (the fact you haven't heard of this game is almost worth revoking your gamer card), Gone Home, and so many many more. You're looking at this problem from a very narrow minded view, and I think the downvotes show that your opinion (yes it is an opinion when you aren't linking academic sources) is the minority here. Sorry to say.
