Without counting the cut scenes, I estimate that my ACTUAL playtime, where I'm actually moving Snake around, is some where between 5 and 7 hours. Maybe more, maybe less. The problem is: There's only one act left. That means that there's, at best, 4 more hours of gameplay left.... Hopefully?
So how the heck did this game get billed as a 40 hour gameplay experience?"
