I'll distract myself from these ruinous spoilers by saying: damn, Metal Gear Solid V is good. Shame about Quiet, who's nothing more than embrassing. It's so clever in every other area, astronomically so, that it's hard to believe it could be so dumb.
While I'm not going to defend a lot of things about V and Quiet, I actually rather liked her superpower, thought it was a really cool idea and tied in nicely with the series lore. I also enjoyed her character and arc. Of course, things like the rain dance and other bits were pretty bad. It'd be a lot less eye-rolling if V was anywhere near as sexy as the other games in the series. But hey, at least Kojima managed to finally achieve his dream of full on naked male ass. Needed more of it, really.
My main issue with V is that its episodic style really didn't lend itself well to the story it was telling outside of one very specific theme which was brilliantly handled. I really don't want to go into full detail (I have a lot of thoughts and most of them are astoundingly spoilery) but I will say that it was my second-place GOTY of 2015, tying with Super Mario Maker and just behind Undertale.
