Starbound: Oh ye stupid missed potential. Chucklefish announced a console port aeons ago, and that was the end for any development of the game. Should have just published the source code on GitLab and gave up. Gutted story/lore, half-implemented systems, terrible movement, awful weapon feel...and yet I've put in over 500 hours into this mess.

Tales of Maj'Eyal: Boy, Darkgod sure doesn't like fixing glaring interface issues, does he? I want to like it more, but there are a lot of deliberate asinine choices with it, including the absurdly lacking weapon comparison.

OpenTTD: At this point, the obstinate developers are causing this game to stagnate. (Don't worry, it's probably safe to break compatibility every now and then.) Honestly, OpenTTD2 with OpenRCT2 as a baseline might be fun. (Shh, I know about Locomotion, it kinda smells.)

Formerly complain:
Pokemon: The worlds biggest media franchise and the games still have terrible mechanics from 1998. It's a shit core built around a great world. I retired from the franchise years ago, so there's no point in me shaking my fist.

Minecraft: I'm not quite sure when the game lost the plot, but at some point I completely lost interest. I think it was right around the Gamepedia/Fandom merger that I lost interest.

Super Mario Sunshine: Thankfully, I think a lot of people are seeing the light on what a shagged mess this game was. Too much of the progression relies on unfun piecemeal content. (And whatever it did good, latter day games did even better.)

Animal Crossing: Boy, I sure don't love how all the personality and edge was carefully smoothed out of this franchise. But I don't have a Switch, so no point in bellyaching about a gutted game I don't own. (Especially as parts of it feel PTW.)

HuniePop: Thank Odin above, someone made a clone without the masterbait. Now I can just enjoy that when the mood strikes instead of cringing.

Ultima 7: With garbage real-time combat, a horrendous inventory system, and the need to feed characters manually, forcing the player to interact with that horrible inventory system, the result is a game that just has horrible gameplay. (I note that Ultima 6 had none of these issues.)

Final Fantasy 7: FF6 was a decent game, once you get the second airship and the game opens up (at least until Ultima shows up, ruining game balance). But then you get this game, which took away the later part (so the game never opens up), reduced the party size, added more unskippable cutscenes, forced a male main character into your party at nearly all times (meaning you can only choose 2 of your party members), added even more excessive cutscenes (including summon animations; who thought giving the final boss an attack with a 2 minute animation was a good idea?), and adding minigames of the sort that does not belong in an RPG. (I really wish the series had continued along the path that FF5 had taken instead of evolving in this direction.)

Baldur's Gate 1 and 2: Real time with pause combat is just terrible (even if it is marginally better than Ultima 7's combat); it essentially manages to combine the worst aspects of turn based and real time combat. Furthermore, BG1 forces you to stay at level 1 for too long (and D&D combat is not fun at level 1 for various reasons), and BG2 forces side quests on you when you're just trying to mind your business managing inventory and spells and doing some shopping.

(Yes, both JRPGs and WRPGs around that same time were not that good, at least the most mainstream ones.)

Every MMORPG ever

Yeah, that's one I can get. Stendhal for example has very little preventing you from getting clobbered; and you have to grind your stats by basically not rushing for armor.

World of Warcraft

I didn't stick around World of Warcraft long enough to experience that, but my opinion is that it would be best for everyone if they just scrapped the thing, pretend it didn't happen, give people Warcraft IV, then make preparations for a Warcraft V with no regard to World of Warcraft.

The best thing I can say about World of Warcraft is that I didn't play another MMORPG after that.

And you certainly have singled out these three before quite often. I've heard a lot of people complaining about the Minigames of FF7 in recent times. And both BG games have varying balance issues, but I understand that BG2 gets off on a better first step, though.

Actually, it's 4, because BG1 and BG2 are separate games.

It is interesting to note that:
* Except for Ultima 7, these games, I believe, came out around the same time.
* FF7 was one of the games released at the time Square seemed to not care about game balance. In FF7, we have such things as the Knights of the Round materia and some of the high level limit breaks; Final Fantasy Tactics has the Calculator's Math Skill abilitiy as well as Orlandu; SaGa Frontier also has its overpowered mechanics, like PluralSlash and DSC. (OK, some of these are hard to get or take a lot of work to get, but Orlandu and PluralSlash are both easily obtained and extremely powerful.)

The Fall - Last Days of Gaia: Still the worst game ever made, story apparently written by a child with a wax crayon, accidentally racist, bugged as fuck, voiceover made in a garage, backtracking from hell, a thousand promises the programmers couldn't keep, "player choice" that's literally 100% fraud and an insulting, throwaway BTTF reference ending that shits on the entire previous story.

... that's it. I don't usually "love" to complain about games.

So, would you say it's worse than all of the following games?
* Action 52
* Hoshi wo Miru Hito
* Ultima 5 NES
* Superman 64
* Big Rigs: Over the Road Racing
* Arabian Nights (PC)
* Every other game that has appeared in the Awful Games block in AGDQ

Edit: Since neither you nor the topic specified that they have to be video games, I could add the TTRPG abomination known as FATAL.

Arabian Nights is well loved here. It has a 3.7 star rating, the same as Cyberpunk 2077.

Almost as good as Mystery of the Druids, which has a 3.8 star rating.

None.
Why waste time, complaining over something, which can't be retroactively changed anyway?

(now patiently waiting for someone to explain to me, how constant complaining over one game, led to the next game becoming "da best game evah!")

For Honor

Sometimes I wonder whether the devs even play the game, as they keep on adding more and more braindead heroes into the game. Worst part is, I can't stop loving the game despite the way Ubisoft handles the updates for the game.

Also one more thing, and this time I'm not complaining on only one game, but a group of FPS games that share the same similarity. And that is I hate how many FPS games would have this trope where whenever you're part of a convoy on your way to the mission location, the games would often put you in an ambush, which then results in the vehicle you were in to get destroyed and forcing you to continue on foot. I often see this in Call of Duty games tbh. Makes me wish for a safe trip once in a while.

Destiny, devs make the meta incomprehensible on a routine basis, but the gameplay loop is too solid for me to ever quit.
