Dude, don’t worry about it, like I said, save your money. If it’s not important to you, it’s better to keep it that way.
It is important to me, I’m gonna keep doing it.
As we get higher and higher frame rate, there are certainly more and more people that won’t care.
But you can’t say it doesn’t make a difference, in blind testing(name of the testing style, obviously) people who freshly walked into a room with a game running and were asked if it was 60 fps or 120 fps guessed right 100% of the time, literally no errors made, they were not gamers. But they did have one training attempt each of walking in on each setting knowing which one it was that time.
So literally everyone -can- see the difference, but not everyone cares.
It is a real thing anyway, unlike cable quality for digital audio.
And to play two copies of the same game at the same time, any 2 members of the family could own it. So my brother and I can each buy a game, and then my mom and sister could play it while we are at work. My sister can’t work, so she has a lot of time to fill but can’t afford to buy games. We do have 5 copies of Stardew Valley, though, as that is a game for the whole family.
There was already a bunch of games my brother and I both owned before steam family was an option. But now games I’m only tangentially interested in after he played them or vice versa are much more of an option to quickly play through to see if I like it too. Before, it just wouldn’t have been worth buying it to find out. And it’s a bonus for the devs too if I do end up liking it, because then I am more likely to buy their next game so I can play it at the same time as my brother.
Gaming is inherently social. Even when we play single-player games, I’m sure most of us have a friend or sibling we talk to about them as we play.
