Even if you are joking, there is a subset of PC gamers that I feel just do it to get in a dick measuring arms race of spending power, and boast about how great their benchmark scores are.
For me, the biggest strengths of PC gaming has always been the flexibility of the platform, and the communities when it comes to a lot of older games. I can still hop on active servers in UT99/2K4, and just recently got in on some private Enemy Territory Quake Wars servers, all of which are some of my favorite multiplayer games, and have been around for decades.
This also isn't even mentioning the plethora of mods that turn a game you have played through ten times into often a completely new experience. Between the OG game and many mods I have played, I can't even count the number of times I have played through Doom (the OG game, not 2016). A lot of this just depends on the games of course, because there sure as hell wasn't an issue with PC players buying Elden Ring or Balder's Gate 3.
