I've, uh, got a friend, ok? Let's say he's a 40-something video game player that's been ignoring this series all these years. He doesn't know about snakes and bosses, liquids or solids, heavens or clones. But the MGS5 gameplay seems good, and the UPF and Quicklooks have been interesting, and he wants to play it.
Does the game give you all the backstory you need if you are coming to the franchise totally blind? ...Or does this friend of mine need to pursue some kind of MGS lore video on YouTube to get oriented? Can a person spend 1 hour of time learning enough to enjoy this game and know what the hell is going on?
My friend thanks you for the advice.
