Not sure why you'd include downloadable titles and F2P stuff for Sony but leave out the same things for Microsoft. They had stuff like Battleblock, State of Decay, and Skulls of the Shogun. All stuff that was published or developed by MS. And we've learned from the PS4 launch that downloadable/indie titles actually DO count. Also some F2P stuff I never bothered with.
So I guess depending on taste one could say 360 had a slow 2013 in terms of games actually brought to the table by MS, but a betrayal? LOL. Also, they have had a good 2014 as well. It's funny, they get criticized for this so called lack of long term support, but then when games like Horizon 2, Fantasia, Spark, etc, are revealed to be cross gen, people complain about them not moving on.
Maybe Sony had such a big 2013 because they have almost nothing for 2014 aside from a yearly baseball update and LBP3?
