It was 1977, and I had just heard of the game when someone posted they were starting to host a game in the school library after school. I asked my folks if I could join. They let me.
I went out and bought the AD&D PHB & MM, a set of purple polyhedral dice, and 2 minis- a human fighter with a 2hd sword and an elf fighter with spear & shield. I made a human fighter as my first PC.
The DM was a Bob Ross/Hobbit lookin’ dude who ran a tough game. My PC was among the last 2 left alongside a human wizard. We both died in the penultimate room of the dungeon in an epic fight with a purple worm.
My compadre only had his quarterstaff, dagger, and a single Magic Missile left when it reared up, cutting us off from escape. He opened with the spell and started swinging the staff. (Mightily, I must add.) I started whiffing with my blade. I landed my first meaningful blow a round or two before a Nat20 got the wizard engulfed.
We traded blows for a few more rounds. Finally, we were both down to 4hp…and initiative was simultaneous. My fighter missed, the worm did not. My PC died, completing the TPK.
…and I’ve been hooked ever since.
