It's strange to see some gamers praise this acquisition as if it will have any positive effect on some of the games they enjoy. In no world will Microsoft decreasing the competition going to be a good thing for consumers.
Microsoft has done a singularly great job valuing the communities around games, often more than the companies they acquired.
Activision in particular was the death of Blizzard. They have a poor reputation which is very well deserved. I consider this acquisition a rescue of IP I’d given up on. I’m looking forward to the next chapter under Microsoft.
For context, it’s important to review Microsoft revenue in gaming (a loss) and how they justify it - they see gaming as a brand play. Unlike most AAA corporations in gaming, protecting the brand of their games and studios is far more important to them.
