Nintendo is by far the bigger deal, but MS also entered an agreement with Valve/Steam but Gabe Newell said it wasn’t necessary because MS always follows through with their promises and they just have a great relationship, Which is saying a lot since Steam is the biggest competitor to the Microsoft Store/Xbox app on PC.
And with hundreds of developers unionizing and MS letting them, working under Xbox will become a very tantalizing prospect for many developers.
Needless to say, this ain’t the same MS we were accustomed to for so many years.
