I give it a solid 8.5, for me it's got plenty of games. I'm predominatly a Call of Duty player, and with BF4 in the mix and a good number of free games and other titles to choose from, I'm really happy with the system. I bought both netgen consoles and I sold my XB1 so that I could purchase another PS4 for my kids.
It's faster and looks better and I don't need to tell my kids how it works because it's very simple like the XBOX 360 was, so my kids and I both didn't have much to try to figure out at all.
I'll boost my rating at least a half point if/when they release the firmware that allows you to use your controller as a wired controller, OR if they just release a wired controller, either way is fine with me. This is my personal preference, I've never liked anything to do with batteries when it comes to a console, with obvious exception being a portable console like my Vita.
I liked the PS4 so much, that I recently bought a Vita, to expand my game library and purchased a PS3 as well.
