I don't understand what your comment has to do with the rest of this conversation? On Demand rightly pointed out that Sony typically only buys studios with whom it has an extensive history, and usually after said developer had made several exclusives for them, whereas MS in the last few years has mostly bought developers who developed multi-platform titles. (Not that I think there is a problem with this because as I stated earlier, most of these devs like Ninja Theory, Obsidian, Double Fine and inXile needed the cash injection). You then intimated that they had been "partnered" for "like every Bethesda game", which only encompasses marketing deals and I don't even think is true for "every Bethesda game" given that includes stuff like Doom, Prey, Dishonored, Wolfenstein and Rage which I don't even think had first-party co-marketing.
You then said "lots of current first party studios were bought". Thank you for the information although I was already aware of that, however I don't see how that is relevant to the discussion. I think most reasonable people don't have an issue with most of the new studios MS bought a few years ago, for reasons pointed out above. However, buying a massive multi-billion dollar publisher who releases everything on all major platforms is a very different thing to buying a small AA or indie studio who was stuggling financially.
