For what it's worth though, the really skilled FPS players have always been on the PC side.
Nerds. The word you’re looking for is nerds.
Biology catches up fast, and it doesn’t matter what gaming hardware you’re using. I’d suggest chasing fun or develop competency in a longer term skill instead of working on your “skilled” gaming clout.
But what do I know, maybe I just need to git gud.
Now, you are free to argue that Quake has been dead for a while and competition isn't as strong but the guy's reflexes seem just as good as they did 20 years ago. Yeah, he's been around for some time.
There are many formidable old school guys in their 40s, even 50s, that still play high skill games and they will kick your ass.
I'm still in the 40-50 range. My reflexes and hand-eye coordination haven't deteriorated significantly. It's not about age, it's about practice, talent, and will.
I still kick some ass in CS, TF2 and Quake. I get tired a lot quicker, of course. But it's mostly my unwillingness to waste my stamina on games rather than work.
PvE games are for unskilled gamers. PlayStation and Switch are the preferred platforms for unskilled gamers. PC is the preferred platform for skilled gamers who can afford a good PC. Xbox is the preferred platform for skilled gamers who are poor (Xbox controllers are better for shooters than PlayStation controllers).
