I've played several Roguelikes where I found ways to savescum. Most of the time it simply involves creating a savefile from the "save and quit" option. You go to where that file it stored, then make a copy of it in a different folder. That way, it can't be deleted when you die or quit and can be recovered whenever you like.
The point of savescumming in a Roguelike is to stick your finger in the eye of the people who made it. On top of that... Just because you can savescum, doesn't mean the game actually gets any easier. Besides, I look at it as "insurance" against "random bullcrap that you have no chance of avoiding". Difficult and Brutal are one thing. Losing a character because the programmer was a malicious jerk who likes to play unfair is quite another. D&D refers to these kinds of people as "bad DMs" and people who play D&D refer to these people as "Killer DMs" and the campaigns as "Character Grinders".
Death because of lack of knowledge or experience or even good equipment is one thing. Death because you entered a room and the ceiling randomly crashes down on your head is quite another.
As someone who plays a ton of TTRPGs/PnPs (as well as GMs), a bad GM is one who does things arbitrarily and without reason, making up things to harass players (IE: Rocks fall, everyone dies, GMPC Mary Sue, setting ridiculously high target numbers for simple tasks, setting high CR mobs in places where they shouldn't be, making mobs work in ways which their predefined intelligence levels would not allow them to do, etc). If you walk into a dungeon without first doing research on it, you're asking for death. If you confront the Big Bad when you are not ready for it (not high enough level, crippled by status effects, empty on beneficial items, out of spells, etc) you're begging me as the GM to kill you. As far as the example you've stated, if the GM has established mentally that the structure is clearly not safe for entering, or is impeccably trapped, the ceiling is going to fall. A GM is an impartial mediator - sometimes things in life just happen. The world doesn't forewarn you that something bad is about to go down, it's up to you to utilize caution and reason to make sure you're not walking blindly to your death. In addition, none of those terms you've used are used in the TTRPG community as far as I'm aware.
Back to thread topic, however;
Any 'sport' game (why aren't you playing sports irl?), everything Call of Duty (and practically every 'military' shooter out there), all the LoZ games that don't feel like LoZ games (here's looking at you, Twilight Princess, Windwaker, etc), all these Minecraft ripoffs (practically anything with that's made of blocks nowadays), all MOBAs, almost every RTS, any game based on a movie/anime/book/comic/tv show (with very few exceptions, one being the walking dead games), any pokemon after yellow, the sims (but only because they milk it as a marketing ploy), any halo after 3, any freemium/pay2win game (practically every free to play mmo, and various other games), any mario that's not truly mario (galaxy, the sports games, the 2d fighting game as well [exception being the mario kart games, idk why]), any game in which the primary feature (intended or otherwise) is grinding - tedious grinding, any sonic game that is not a 2d or 2d racing game in which you are a running animal, any wrestling game (wrestling on tv as well), any facebook/app/most flash games, any game in which you as a physical human being are the controller, any game based primarily around using gimmicky tech (the human controller mentioned previously is one of these, as well as that one game that uses sunlight, or the DS's touch screen, or the 3ds's '3d' functionality, etc), any game designed to appeal to children, any kingdom hearts (if they were made in the same vein as that one rebirth video, however,....), barbie/bratz/lego/etc games (I mean, who thinks this is a good idea even? if they've bought barbies/bratz/legos/whatever they're going to be playing with those things!This is a really ty marketing tactic), as much as I love love LOVE zombies they are being milked to a pulp - so practically everything that has zombies in it nowadays, splitscreen games, etc, etc, etc.
I'm not sure how many 'cherished' games are listed here or fall under these categories, but this list would be a lot longer if I could remember all the things I hate (a bit of honesty here, I lack the ability to actually hate anything, so...).
