I’ve been gaming for over 40 years, and served as plot head of the national plot committee for a LARP that I helped found. As a 9-1-1 Dispatcher, I find it therapeutic to create custom battle maps...and to sell them is a bonus! The idea behind the Instant Dungeon Crawl line was 1. To help cutdown on DM prep time and effort. 2. To create map settings that aren’t in abundance (like my popular Planar Adventures and Aquatic Adventures). 3.to spark an inspiration for DMs. 4. Affordable gaming resources—I remember being a young gamer wishing I could afford a lot of cool stuff.
Each map is playtested on Roll20.
Here's a Youtube commercial I made for my products (headphones recommended for maxium enjoyment): https://www.youtube.com/watch?v=E7G45vyL_FU
