Okay lets give this a stab
PS3 - 8/10 - Very solid effort, lots of interesting new IPs and favorite staples.
360 - 7/10 - First party was a bit lacking, but the 3rd party releases still meant it had a very nice year.
Wii - 1/10 - This is just a Just Dance machine now right?
PS4 - 7/10 - Like the 360, First party has been underwhelming, but damn, those FIFA and Need for Speed releases. Third party really helping the new hardware shine.
Wii U - 8/10 - From a game perspective, after a dire first 6 months, the Wii U has really come into it's own for me lately. It's certainly got a couple of my favourite home console games of the year on it.
XB1 - 6/10 - I'll be honest, I don't have one yet, but it's had a pretty solid launch, however it's too expensive IMO and the majority of games are better purchased on the PS4.
3DS - 7/10 - Sales-wise it's been a stunner, but with the exception of Luigi's Mansion 2 and Zelda, most of it's big hitters don't really appeal to me (not really been into Pokemon since the original GB ones, Animal Crossing never clicked) and the game lineup is pretty limited in scope (great if you love RPGs but, I have other preferred genres)
Vita - 9/10 - Despite the lack of massively high profile releases, it's had a fantastic year for me and been my most used system by far. Highlights have been Hotline Miami, Thomas Was Alone, Soul Sacrifice, Killzone and Tearaway. But as racing games are one of my preferred genres, it's the presence of titles like WRC4 and Moto GP 13 which have really helped elevate this to my preferred system of 2013 as I spend a lot of time commuting to and from work.
