You do realize Microsoft has been in gaming business for over 20 years, right?
You do realize they SUCK at it, right?
Not even EA where it is a commercially successful, artistically bland sucks, but both commercial failures and artistically bland sucks.
They objectively suck in super obvious, economics of scale and critically measurable ways.
Just skimming the top:
(a) ran industry darling Rare into the ground after buying them from Nintendo
(b) got effortlessly routed by Sony this past console generation, is overall the least successful console developer with a smaller global footprint and a much smaller legacy than Nintendo or Sony
(c) Halo is their only successful game, developed by third parties, and it sucks now
(d) made Shadowrun a first person shooter because everything on Xbox needs to be a first person shooter
(e) everything needs to be a forgettable first person shooter
