1: First store I bought a TTRPG: probably Amatos toy and hobby in Middletown, CT, somewhere in the early 80’s. Its still in business? https://www.amatosmiddletown.com/
2: Favorite TTRPG game world: Oof, this is hard because I’m not much for published game worlds. That being said, I love the Feng Shui 1E design of intricately tying the world/factions and gameplay and leaving that introduction static in the supplements so everyone’s game world advances independently.
3: Published NPC that had a lasting impression on you: This one’s even harder. All of my groups were DIY world designs, even when we did borrow from published worlds. As a GM I drew the most inspiration from the opponents in V&V’s _Most Wanted: Volume 1_
