C'mon guys. Let's take a trip down memory lane.
I played a true game of 1e maybe four or five times in my life. The first few times was when I was learning to play and even then I got so much stuff wrong that it could be considered a "house rule". For the record, when you bought quarrels (as in, the kind for crossbows) I thought that meant "arguement" and the monster was supposed to have an argument with the DM. So I made the monster roll a saving throw. If the monster lost, it dissapeared. To my eleven year-old brain, this made sense. Then again, it also made sense to throw rocks at girls when I wanted them to like me. I finally figured out what a quarrel was when I was 12. I stopped throwing rocks at girls I liked when I was about 26.
The one true time I played 1e was right before 3e was released. I made everyone roll 3d6 and wouldn't let them adjust the attributes or rearange the numbers out of order. I also made them roll hit points and wouldn't let them reroll. The fighter had 5 hit points. The cleric had 2. Then we played Keep on the Borderlands. As my one token of goodwill to my players, I let them use out-of-game-knowledge. So if they knew a secret door was in a given room, I'd let them look for it and find it. After the party defeated the kobolds (with only two PC deaths!) they moved on to the orc caves. They had found a potion of invisibility. My buddy John, in the most amazing display of metagaming I've ever seen in my life, drank the potion and navigated the entire orc complex completely by memory. He took all the unguarded treasure and snuck out. He had not played that module in over a dozen years. It was outstanding. We gave him a standing ovation. After the commotion died down, his wife turned to him and said "you can do all of that but you can't remember to take the garbage out on Tuesday!?!?!" Priceless.
In any case, 1e has many fond memories for me, but I'm still happy to be a 3e gamer.
