Or maybe publishers finally found another competitor and a more trusted company than Valve?
It's publicly known that Epic pays a lot for these exclusivity deals. I have no problem if a publisher decides they don't want to publish on Steam, and I use most other stores. I have a problem with a store shopping around games that were already announced on other platforms (games that look good and have almost guaranteed success), locking them to their store.
Is it difficult to understand that, as a customer, I do not see any benefit from reading a piece of news like "change of plans, this game is now not available on any other store but this one" every other day? This goes against what PC, as a platform, is all about, and what made it what it is today.
