They've been pretty innocuous so far.
History just makes me sceptical. Maybe being innocuous is the problem? why make acquisitions if you don't know what to do with them?
Maybe we already know MS M.O. and right now they have clearly a plan to go full GaaS route, although they don't know how to achieve it. There is no case of sucess coming from Microsoft Games Studios and I can't blame the devs, but MS strategy.
Even if they did make acquisition of talented devs I just don't give anymore benefit of the doubt, they have to earn it. My fellow xbox fans could just dismiss as a fanboy drivel, but come on...there is a limit for everyone.
When we talk about Sony, we have seen the results of their work on WWS. Playstation brand was cultivated along the years through the accumulation of user trust and this is something they tell in their report which really makes sense: "To reinforce content IP, SIE will accelerate the enhancement and rollout of its portfolio of exclusive PlayStation titles. As a result of cooperation with in-house development and partner companies, sell-through of PS4 software titles continues to grow, and the intention is to further enhance the lineup with compelling content ".
"cinematic movies" they say, but sony has a clear commitment to quality games and therefore it is no wonder that its studios have been improving over the years while Microsoft has failed to do the same.
