I don't remember Quest for Glory 4 all that much, perhaps the least out of the seemingly neverending cascade of psuedo-fail and Sierra that the QFG games were, but I do remember a very very stupid thing that happens.
In the first 3 or in-game days, before you can get to the "open world" (read: more stupid puzzles and Monty Python jokes) you have to do a very specific series of actions. Firstly, you have to talk to a gargoyle-type creature in the inn... though accessing the inn itself is an ordeal due to the game's annoying day-night system. If you imported the character from previous games (like I did) then you might have the skills to break into your room, but that doesn't make it any less dumb.
You also have to go an equally annoying series of mini-game esque puzzles in order to meet the town's local mad scientist guy. These puzzles. So annoying. Uugh. I hate them. All of them.
The last one is more complicated, and perhaps the most contrived, and lasts the longest. If you don't do this, it bites you in the ass much later. There's another one that also occurs within it, involving a werewolf and pointy farming utensils. If you don't save him, the game becomes unwinnable.
Noticing a pattern here? "Go to this place, that you have no indication to go to, at this specific time, with this item, having had talked to this person about this here that you learn about over there, and then do the thing, which then gives you even more time-contrained bullshit tasks that don't advance the plot."
I attempted to do the start of this game around 20 or so times, because the game became outright unwinnable in so many situations. Even worse is that not even all of these are actually design decisions[[footnote]] ridiculous bullshit shit out of the Sierra gravedigging machine[[/footnote]] and more hilariously bad bugs, technical errors, and other batshit insane crap because making games that actually work is haaaaaaaaaaaaaaard.
Cue me screaming, having a breakdown, and then crying. I did end up beating the game, eventually, with Elrog the Flaming Drag Disco Queen. Took me 87 in-game days because of those God damn sidequests.
