I'm not biased at all -- the objective truth is that most of the biggest game studio acquisitions that MS has made over the last two decades have failed, died, or left MS.^That's biased, and shows you're actually ignoring history and simply focusing on their mistakes from the beginning of this generation (of which yes, there were many) instead of their actual, overall history.
Their entire sports division died, Rare is now essentially dead, Bungie went from one of the most beloved studios in gaming to... Destiny.. And then eventually left Microsoft completely. Microsoft took the Halo franchise froim them and now we have.. Halo: Infinite. The Lionhead acquisition did not go well. The Twisted Pixel acquisition also did not go well, and they left. Digital Anvil was dissolved and there was no sequel to Freelancer. Microsoft is a place where companies go to die.
The number of notable studios that have stayed with MS and are actually better off in 2020 than when they were acquired is very, very small. Not saying that they don't exist, but they are dwarfed by the many, many cautionary tales.
