I'd like some examples, actually, because I'm not seeing how you could possibly get more out of MGSV's characters and narrative than any other MGS game.
I didn't say more, but about the same at the very least. I'll make a short list of things that I thought about further or saw in a new light after MGSV:
1. Huey and the pos that he turned out to be obviously was a whole new take on the character and the character type within the MGS universe, also made me think about Otacon (how different he was from his father) and the way Huey eventually died (suicide).
2. Miller as a whole and his connection with Solid Snake. Loved Miller in this game, so bitter and all business.
3. Liquid killing Miller in MGS1.
4. Ocelot supporting Liquid and Solidus.
5. Ocelot hypnosis technique and Ocelot in general. A character that we saw in a different light pretty much in every MGS game, and MGSV was no exception.
6. Paz
7. Big Boss having two fortresses and dying twice between Metal Gear 1 and Metal Gear 2 (this blew my mind, Kojima actually justified something like this within the context of the actual story of the universe instead of it being left explained away by just being a game and the villian coming back just because).
8. Quite was just too damn awesome and felt like a true comrade in arms, one that you fought a long side and would lose permanently eventually. So good.
9. The war economy.
10. Zeros character was of course expanded upon and made me feel more for him, and of course remember his death in MGS4.
11. Liquid and Psycho Mantis in MGS1. Not to mention REX.
The list goes on and on for me, couldn't have asked for more from a final entry in the series basically.
If the game was smarter about how it brings the tapes to your attention, and if my allies talking would temporarily pause it, or ideally be muted while listening, I think it would have been a better alternative to the codec than it currently is.
Huh? It tells you pretty much every freaking time to listen to new tapes. There is even a button prompt when you are in the helicopter (tells you to press triangle with a yellow tape icon) that specifically takes you straight to the tapes. I always devoured these tapes in the helicopter so I could give them my full attention, which is what you should do instead of listening to them with your attention distracted during gameplay.
