Seriously though, it's hard to compare a game like the Order to TloU, Tomb Raider, Wolfenstein, Evil Within, even Ground Zeroes because the amount of gameplay it offers(From what I've seen). No replayability aside from collecting trophies(Which every game has) or collectables, or wanting to see the cutscenes again(Which I've never heard of anyone replaying a game just to see a cutscene again.)
It's a hard game to compare.
Multiplayer is extras? And playing these 'extras' are just for getting your monies worth? Like...what are goals or getting something you want out of it? I replayed Metal Gear Revengance in order to save up credits for the Gray Fox outfit/sword. Because the game was fun and replaying it wasn't a chore. I didn't play it just so I would get my moneys worth, I replayed it because it was fun.
