Minimal prep effort is why I put out Mothership adventures that have very defined crawl procedures. For every module I make moving forward, I’m also going to include 11x17 VTT/print & play maps, VTT tokens/print & play counters, player aids, and warden aids. This is for every module, including pamphlet modules. Even if you’re getting it entirely digitally, you’re getting a boxed module with everything you need to play. I do plan to offer POD counters and boxed versions of everything as well. However, this is all the kind of prep that you need to run something OSR adjacent, these are not linear adventures, they are boxed toolkits.
