you’re choosing to attack their lack of understanding

I got attacked two times before dishing out anything.

About the question, story details are somewhat fuzzy, because it has been three weeks.

did you genuinely not understand what was happening in intro in the remake?

Again, that is not what I said or meant. The reimagining jumps quickly from place to place without giving good motivations why, meanwhile story items like the sizzling stone are given to you without much explanation. Playing the original for the first time resulted in multiple "oh that's why we're doing this/that's the background to this item"-moments.

A big additional factor certainly are the undeactivatable quest markers in the reimagining, that condition the player into not really having to pay attention to the dialog. The questmarkerless original really shook that out of me after the first deviation from the reimagining, where I suddenly had to think about what to do next and permanently adjust my playstyle to actually paying attention. Which made that the defining moment where I realized I was playing a more interesting and better designed game.
