I find the dismissal of FPS fascinating since I figure you would want a consistent smooth experience in a game that is going for action and immersion.
It's competing narratives.
People complain and want truly open world and not zones.
People want amazing graphics and high fidelity.
People want a high framerate.
It looks like Starfield is going to sacrifice a bit on the FPS side to have more of the top 2. Some might not like the choice but most won't care.
It's like the quote if my grandmother had wheels she'd be a bike. Starfield doesn't seem like it is trying to be or wants to be a game requiring a lot of skill. It's not selling itself on tough boss fights. Maybe if that is how it was selling itself they would have made different choices in regards to FPS or the complaints would be taken more seriously.
