That stuff adds up when you toss on 4-5 hours of 1080p movies and cut scenes plus a game.
Fortunately no western developer is dumb enough to think its fans want to watch 4-5 hours of pre-rendered cut scenes. That's pretty solely in the realm of FF and MGS, two games that haven't been fun for me since the early 90s, in part because they became more about watching incoherent cut scenes and less about doing anything.
