I've had it since launch and I'm around a 7.2 in terms of overall rating. When I first had it, it was much lower, but it has improved. At launch it was so slow, I had tons of errors, and there's still no multitasking. Game wise I had 4 games until this August, now I have 12. It has improved and gotten faster in terms of overall performance, but it's going to be my secondary console. The virtual console is complete garbage and I can't believe they are this slow with releases. 2014 will be a better year for games as well.
1) 7.2
2) Around 200 hours since November 2012. Not that much.
3) 3D Land is my favorite, it's very good, but a little too familiar. I also enjoyed Lego City, and Mario U. Sonic was disappointing, and I haven't played Zelda, 101, or Pikmin yet.
