I think No Man's Sky is also in the same boat.
I mean games which keep releasing further content over long periods without charging extra for it. Surely the amount of new sales eventually dwindles considerably. Is the cost of new content once you have the core game this low or…?
That's the downside on if a major publisher agrees to publish your game. Typically the big ones will exert control over the game development; NMS is mostly indie so they can do what they want.
If it was up to some bigwig at EAVISIONUBI CORP. the game probably would have been dropped after it failed. CD PROJEKT RED also self-published, so it was entirely up to them on fixing Cyberpunk or not.
