R&D as an analogy, if the game does something new, creates a new experience then it's worth extra because you can't get it anywhere else until poor copies appear in a few years

Replayability and Flow. Length doesn't matter look at AC games. But I could re run RE games or Respec new build in Elden Ring and feel the rush of making decisions on the fly and anticipating the dodge when an enemy could almost touch me

Beauty, same as movies I guess when you get to experience people's creativity, not in overproduced generic stuff like Amazon or Apple TV shows or Asscreed, but when there is a good art direction. Good design beats out fidelity any time
