Most of the talk around Bethesda has been getting the Games & Studios but MS also get game engines in ID Tech (Doom etc), Void (Dishonored), & Creation (Skyrim/ Fallout
). They also get some streaming tech which might help xCloud -
At its 2019 E3 showcase, Bethesda revealed Orion, its patented cloud streaming SDK, which it says its easy to integrate into existing games. Bethesda claims Orion allows games to run at "max settings" with minimal bandwidth usage, even if you live far away from a data center. To demonstrate these claims, Bethesda and id Software who are leading development of this SDK, demonstrated DOOM 2016 at 4K 60 frames per second, running on a smartphone.
