These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Quest for Glory II
Anvilicious - The message that wizards get from the Dervish ("Wizards sit and study problem while a hero solves it") and Erasmus ("What good is magic or knowledge unless you use them?") and the Nonstandard Game Over that they get if they decide to stay at the Wizards' Institute of Technocery might be laying it on a bit thick... or maybe Some Anvils Need to Be Dropped.
Demonic Spiders: Like So You Want to Be a Hero, the worst monster you can run into is a bigger, meaner variety of saurus, this time the terrorsaurus. Very quick and very strong, they can take a lot of hits and there is utterly no reason to fight one besides puzzle points for the Fighter class (and proving how Badass your character is).
The Fan Remake take that Up to Eleven by turning the Ghouls into spellcasters. Oh, and they still retain their chilling claws ability.
Scrappy Mechanic: In the original, you could only rest (to quickly advance time) in your bedroom. Since the sleeping rooms in Raseir were only available at night, this meant you had to stand around doing nothing for a long time, since there was very little to do. The remake fixed it by letting you rest in most places and putting a few convenient time-skips at points where the developers knew people would run out of stuff to do.
The street maze was one too, but since you had to navigate it without a map at the very start of the game, a lot of first-timers were put off by it. The remake gave players the ability to pick a simplified system and added landmarks and skylines to make navigation easier.
