I'm fairly drink so I can't really read. Did you in own an Xbox 360 because that opens you up to a ton on games that, whole older, still look good and play really well. Plus the Xbox has features and apps that the PS4 don't. As far as games, it easy enough to see which games aren't on other consoles. N if you have a gaming PC it might not be worth it. The features it has will be available on PC and then some.
If you do get an Xbox One, add me. I'm buy you a new game as a welcome to the system. Whatever you want.
