Alright, I'll limit it to just pet peeves.

Tutorial sections that just suck. Some don't explain enough, others treat you like you've never played a game in your life. Or, when they interrupt you to explain a mechanic in great detail, but it's too much of an info dump, and you're just left wondering wtf they just said. One game that I really liked how they did it was BG3. There's a tutorial, but you can also turn it off on future runs. Worst tutorial I think I've ever seen was Xenoblade 2.

Games (and really any consumable media) that just don't know when to end. There are very few games I've completed, mostly because I get bored. The game overstayed it's welcome and I'm done. The grind isn't worth the final boss fight or whatever is at the end. Generally, it's because games (especially RPGs) think grinding is a "fun" mechanic when it's more of an imbalanced game. Take, for example, Expedition 33, not once in that game do you need to run around grinding levels. You can successfully go through the entire game, only going to each stage once. Fucking fantastic. But then you have games that just went too far with things. Some games, like Skyrim, CP2077, (especially) Hogwarts Legacy, I only know the ending to those games because other people beat them. Ex33 I got 52/55 achievements (just need to win the gestral games and find whatever record I missed). I beat that game entirely in 74 hours. My first run of BG3 (53/54 achievements, only missing the bard one, because I think it's boring), first playthrough was maybe 120 hours (currently over 700 due to multiple playthroughs). Skyrim... 146 hours... 27/75 achievements. CP2077, 133 hours, 18/57 achievements. Hogwarts sits at 50 hours with 19/45 achievements (that game should be a 20-hour game at most).

Games that don't really respect your time. This one, Nintendo does a lot. Actually perfect example is Breath of the Wild. It's a giant fuck off world that's mostly empty, peppered largely with the same enemies throughout the whole thing. You have a weapon mechanic that encourages you NOT to fight (just get some good weapons and head off to exactly where you need to go). The cooking is bullshit, no recipe book, no making a bunch of something, a stupid cutscene every time. And the entire poop joke... like getting 20 for a poop joke would already be too much, but collecting 900 with (IIRC) no fucking way to track them.. Or the fact that the way Nintendo expects you to get arrows is to grind out rupees to buy them. And the exploits used to get arrows or rupees quickly, in a single player game, they actively tried to patch out. That's just one game, Nintendo does this on SO MANY GAMES, which actually pushed me to "fuck Nintendo" and I didn't buy and won't buy a Switch 2.

Some games are combos of these. One game I really like, but I always hit a wall is Satisfactory. Once I get to trains/aluminum, it's just not fun anymore for me. I work 40-80 hours a week (sometimes I work 5x12s and 8ish hours Sat/Sun)(only sometimes, usually closer to 50 hours a week)... so all the extra planning and time to making a factory... like I just don't have the fucking time. Same thing with Dune Awakening. The first zone was the best. Getting your first Orni wasn't too bad, but it was already starting to push it. Having to fucking pay taxes in a game... Oddly, it was about the time I was farming up aluminum, I quit that game too. Maybe I have a pet peeve with aluminum in video games...
