Before I got my gaming PC a couple of years back, FOV wasn't even a thing on my mind. I knew no different.
Then I had my eyes opened. And now everything I play on PC I do with FOV at 90-95 if possible (on 55" TV playing from the couch). It's so much more immersive, you see so much more, it feels so much better. But it's not until you go back to console games with low FOVs that it then really hits you. Games like GoW 2018 (and not even a FPS) are genuinely a real struggle now, feels like walking around looking through binoculars and so claustrophobic.
So yeah, it's a big deal for me now. But then so is 120fps. It's like all things, you don't know what you're missing until you get a taste, then it's a struggle to go back.
