That's what we call "git gud" and is a common response to people that say a particular game is too hard.
OK, let's say I just shelled out $60 or so for a game. I think that entitles me to play it at some level? The break point is actually not when I can't do something, though that may be the case, but when I stop enjoying it. I then have a decision to either struggle on or quit the whole thing. I should have another choice, which is to set an "easy" level (I'll discuss cheat codes in a minute).
All this stems from the observed fact that there are some players that are just mind-numbingly good at video games. They defeat games at the hardest level and complain that the game is too easy. That's fine, and good for them, but some of them seem to get offended by the idea that some people either can't or don't want to put in the time or effort necessary to get that skilled. Why this should offend them escapes me, but it seems like the "jocks" at school that are naturally good a games sneering at the fat kid that struggles to run round the track once. If he'd just work harder, they say, he would succeed and be wonderful like us. I'm sorry guys, but some of us just don't want all the hassle that entails, we just want to spend a few hours enjoying the game we just paid good money for.
I see that most games do have "easy" levels and that's good. I'm less happy about cheat codes, because they can have side effects. I believe they are put in to help developers and testers to work through the game without constantly dying, or grinding to get a particular resource. That means that they may not work as described. I'll give a recent example. I'm playing Starfield and I hit a situation where I was fighting through long corridors being poisoned by gases and attached by robots. Even on easy level I just kept running out of health. I found a cheat code that stopped me dying, and got through it with a huge sigh of relief. Then I found that all my previous saves had gone. Apparently using the cheat codes changes the name of the save file or something.
I should emphasize that what I say applies only to single player games. In MMOs, some people do cheat to get the most powerful weapon or whatever and that's wrong as they are getting an advantage over other players. If they can't compete, then they should choose another game, though most MMOs in my experience segregate players at different skill levels in some way.
