The key to our awards is not the release date but when we played the game in question.

Best Gaming Platform 2013; And the Winner is 

The Vita

This little device has changed the way I play games. I'm far more happy playing short experiences now than I was before and that is due to titles like FIFA, Zen Pinball, Unit 13 and Killzone. This may just be because I have a family (and no access to a PS4) so relying on my Vita while my wife watches X-Factor has become a norm. For this fact alone the Vita deserves the highest place in the echelon of gaming platforms.
Also it would be amiss for me not to mention the amazing variety of titles the console now has from AAA to Indie.
