Another catalyst is one company buying another. I cannot think of one example where the acquired company’s product/services got better after a M and A.
I feel like there have been some positive outcomes of mergers and acquisitions but I am having trouble thinking of them. What comes to my mind is Meta acquiring Oculus, Activision merging with Blizzard, and Microsoft acquiring Minecraft. All of those have led to a shitty Russian nesting doll of launchers and DRM.
The positives might be harder to note though. There must have been a couple times where some kind of acquisition has brought a series into the mainstream.
I know a lot of people prefer the classic Fallout games but I do wonder how people would be aware of the series if it weren’t for Bethesda buying the right to Fallout for example.
