Phantom Pain is very enjoyable. I have yet to finish the campaign due to the retroactive karma system that was put in place. Now I'm demon snake, smothered in blood, with a massive horn sticking out of my forehead and I lack the motivation to redeem myself morally by visiting the zoo a million times. You can tell it's made by Kojima because it makes absolutely no sense yet is somehow a lot of fun.
I too also suffer from a massive backlog combined with a disinterest in playing video games. I have over 700 games and I've either finished or decided I didn't like only about 100 of them.
