I didn't think I was spoiling anything. I mean, you get a good look at her face right before she bursts into flames, and all this is about 45 seconds before you actually control anything in the tutorial.
I beat MGSV a couple weeks ago but never got around to reporting back here. Basically, the game is still absolutely fantastic. I have never played a more fun action or stealth video game, and still pick it up from time to time. I would have liked more story, but what plot was there is legitimately important, especially some end-game information you get for finishing the story. Super spoilers ahead
Playing Xenoblade Chronicles' New Game+ mode sounded fun at first since I could carry over a lot of weapons and equipment. But fighting bosses is no fun now at the beginning because they all die in one hit. :c At least I'll have the satisfaction of obliterating the ones I found initially impossible in a matter of seconds.
