Google provided to the CMA alot of proof that Microsoft's Bethesda acquisition was what caused to close Stadia
This may not completely related to this acquisition, but Google's proof is rubbish. Stadia failed for a huge combination of reasons, but lack of Bethesda support is not enough to shut down an entire platform. Stadia failed to attract enough customers because:
1) Cloud gaming is new and there are fewer customers than the established consoles or PC
2) Stadia had no exclusive games at all, there was no reason for anyone to choose Stadia over other platforms
3) Stadia games had to be purchased just like any other platform, however they almost never had sales. Often the games were cheaper on Epic, Steam, or on the consoles
4) The selection of games was smaller than other platforms because Stadia games had to be run on Linux. There was a whole porting process for developers, and not a big enough market to justify that cost.
5) Google has a terrible track record for consumer products. They needed to be OK losing a lot of money to get this off the ground, and they are never OK with that.
6) The users they did have didn't find value in paying for the subscription. Their subscription cost $10 a month and offered two free games a month. That is not competitive with either Microsoft or Sony.
I could go on and on, but I think you get the point. Stadia didn't know what it wanted to do, wasn't committed to success, and cost more. Recipe for failure.
