I was 4 when the first DOOM came out, 7 when Quake was released - I LOVE me some fps games.
But I don't find playing online fun anymore - The first 3 days are great, then you've ranked up a bit and start hitting the rampant cheating, and you realize it's just a waste of time sitting for 20 minutes in a game where some 12 year old (or much worse, some 30 year old) has just bought hacks to feel good.
To be honest - I actually blame the automated matchmaking systems more than anything else.
Give me the good ol' server lists back, where a real person is an admin, and you can make a group of friends. This monotonous, automated, matching bullshit sucks the soul out of most games. It's not fun anymore, it's designed to be a chore to prove that you're "better", with an intentionally game-ified rewards systems built to trigger gambling impulses.
Another good niche game with virtually non-existent cheating is Midair. It's mostly old-school FPS players reliving their Tribes days with good admins global banning the rare cheater.
As an aside it's recommended to keep latency under 20ms to stop motion sickness in VR.
Singlehandedly killed my desire in multiple games.
Up near LE/LEM ranks - no one is using the obvious hacks anymore. Instead it's things like a small autosnap radius for heads (ex: mouse within 3px of a players head? snap to head on fire), auto-recoil control, and map awareness hacks (4 went A, we go B)
It's a similar problem in Valorant - the goal of the cheater in the higher ranks is to get an unfair advantage with just enough of a cheat to leave the other players wondering if they actually cheated at all.
Hell - there are actually hardware cheats now - ex: mouse that will handle recoil for you in these games now.
It's destroyed my interest in the competitive FPS genre entirely.
