SO and Ryse not own by MS, all others he listed are own by MS.

When a 3rd party developer develops a game exclusively for a platform, it's a first party game?

I've seen peole claim that games like The Wonderful 101, The Order:1886, and Heavy Rain are 1st party new IPs despite all of those games being developed by 3rd party studios.
