Having cheated at a few competitive multiplayer video games over the years, this is one of a few good answers, particularly when it comes to FPS. That, and many such video games induce boredom so quickly, and almost always the reward at the end is not worth the time spent getting there. Sometimes I'm glad I didn't waste my time getting to end-game content just to find out it was more of the same (or garbage) anyway. I don't play multiplayer games anymore, at all really, unless it's cooperative/integrated like Elden Ring.
I think something like chess is different; cheating in video games feels more similar to hacking around some software just because you can and it's interesting.
I cheated in Arma3. Moneyhax - just wanted to practice flyin` some jets in a decent combat environment without grinding endlessly. Glitched invisibility - real hillarious for couple hours. Occasional item duping to jumpstart combat readyness of our group (somewhat hated this one). Cliff glitching to enter inside of them and store loot on persistent servers. Most of the cheating came out of curiosity - to explore and push the boundaries of game. Nevertheless, the very best Arma3 gaming experience came out of fair and square pwnage operation of our group on public server. Infil via chopper, 2 snipers @ south / east hills, 1 AT/spotter, 4 people assault squad, myself as a commander miles away on an island watching through UAV. We cleared like 20 people in couple minutes and got a thropy tank without taking (!) any casualties. Planned and prepared for about an hour (+ ~3h to build up necessary supplies).
the game might a big part of their life, and being perceived as a good player puts you higher in the pecking order within your friend group
