1. Uncharted 4 was very disappointing. Nowhere near as good as the other Uncharted games, but it's still a good game. Just doesn't come near the greatness of the other games, especially Uncharted 2.
2. ReCore. I still think the game is great and love it, but I wish they had a bigger budget and more time to truly work on it and to fix its problems, since the game has so much potential to be a big new IP for Microsoft. What's there is good, it just needs to be more refined.
3. No more Switch info until 2017. The teaser was great and showed what the basics of the system were in a very simple way, but I wanted more info in 2016. Now we gotta wait 3 months again.
4. United Front Games closing down. One of my favorite games of all time is Modnation Racers which they developed so it makes it more of a shame for me, since I had always hoped they would be funded to make a sequel on the PS4 by Sony or something.
