We did.
We also bounced off it fast.
But there were even editorials by Gygax that were angry rants against people who didn’t use the rules right.
I do find it odd that so many folks here claim they didn’t use the rules if the book if the game they claimed to play. That was just the norm everywhere I went back in the 80s.
No, you didn't. And no, it wasn't the norm. Look, I don't want to say, "Your lived experience was wrong," but I am going to say that your memory ... is incorrect.
Here- let's start with some of the basics. Real basic stuff.
Did you use Weapon v. AC? That's an easy one.
Did you make sure that Elves could not be Resurrected? And Half-Orcs? Only reincarnation for them (absent a Rod).
Did you consistently use the item saving throw table? When you fell into a 10' pit, did you
inter alia roll to see if your potions survived?
How did you handle initiative? Be specific.
What roleplaying rating did your characters normally get, and how did that affect the money you spent to advance in levels?
Did you have all of your different AC values calculated? Attacks from the back or side (dex and shield), multiple attacks (shield), etc.?
Did you ever use the multiple attacks due to weapon speed factors? Did you use weapon speed factors?
Did you correctly do morale checks? If so, how so?
How did you handle missile combat? Were you following the rules regarding firing when others are engaged in melee?
How did you handle combat with helmed/unhelmed opponents?
What rule did you follow in terms of "death" and/or zero hit points?
How did you handle spellcasting in combat? Did you have the casting times memorized?
How did you handle the specific rules regarding (") and the differences between indoor/outdoor and specific activities (incl. spellcasting and combat) that did not follow those distinctions?
Did you apply appropriate modifiers to the accumulation of XP?
Should I keep going? I have played a lot of 1e over the course of decades. I am intimately familiar with the rules. I have never met a single person who has (or who could) play AD&D 100% RAW, and I have never met anyone who is familiar with it who has claimed that they have.
If you are that unicorn, please tell us more! Really and seriously. If nothing else, I'd love to know more about how you handled initiative under RAW.
