I bought mine in April and I didn't do much with it other than play through Resogun in an afternoon until Alien: Isolation came out. I then picked up Killzone: Shadowfall and I enjoyed it's different ideas from other FPS. So far those three games are it. I like Infamous games, but I've played through both PS3 games this year so I'm not ready to dive back in yet.
To rate it's performance and capability, it's a 9. To rate my enjoyment out of it to date, a 7. This will increase quite a bit with releases though.
My first year with WiiU was similar. There were a few good games(Pikmin 3, Mario 3d, Rayman), but it wasn't until this year that it really started to stand out in quality.
