500+ people for a videogame is insane. That's kind of cool - despite the problems they faced. I feel like these games don't reflect the number of people being hired for them. I'm not sure it should linearly scale (probably not), but they seem like they scale down rather than up with an increase in staff.

I feel like modern producers are missing the forest for the trees. Games are not successful for being infinitely large. Skyrim is small by today's standards. So is Oblivion. So are hundreds of other contemporary indie games that have captured the hearts of thousands.

It's not about more content. It's about content that feels deeper. Depth over breadth. Baldurs Gate 3 proves that out. I don't think you can expect these large groups of 500 people to all work towards a deeper game without major changes in roles. I'm no expert by any means, but I am a software engineer with some side-hobby game development experience. I think games are flat because mechanics aren't growing with the power. We're getting graphics, dialogue, and places. But the places aren't any more "deep" than 5 years ago. The dialogue isn't more interesting. The graphics are nice - but hardly why people buy games. I want to capture the "anything is possible" feeling when I hop into a game. BG3 recaptured that illusion for me for a long time.

TL;Dr developers can't throw more bodies at this problem. It's an artistic and structural problem. They need to reframe how they create the art. It can't be mass produced without ending up flat.
