For an interesting yet sad comparison, see Rockstar vs Avalanche - GTAx vs Just Cause 2 and 3. While the modding future of JC3 is precarious due to Denuvo DRM (blame Square Enix), JC2 is pretty much the gold standard.
Studios that get too large for their own sake and get completely disconnected from their userbase. They no longer see the players, the fun or even the game - they just see the numbers. Business guys thinking a video game company can be run like a bank.
The devs get blamed for it, too; as if they had anything to do with it. These decisions are made high above them.
