One time I built an arena out of kinetic sand, with shaped obstacles and dunes and stuff, then scraped a grid into it for battle. I built some working pit-traps into the sand itself that only collapsed with enough weight was placed on them, and I glued small weights to the bottom of the player minis to trigger the traps, while using light plastic kobold minis for the monsters, which did not trigger them.

The next week my girlfriend responded by running her game with a functioning sewer system with variable water levels.

...my wife came home from a chemistry demonstration with a cooler full of dry ice: we thought it would be fun to fill the master bathtub with hot water, dump it all in at once, and watch what happened...

...besides the obvious violent commotion, our entire house filled with a waist-high impetrable fog, enough that we panicked and quickly evacuated the cats lest they be overwhelmed by carbon dioxide...

Moooom, can you turn on the fog of war machine? I can see parts of the mortal realm again.

I took a breaking DM’ing after running a group for nearly a decade. During that time I started playing 40K. Which, some may not know this, is quite expensive if you don’t know how to 3d print. So I picked up the hobby.

Now that I want to DM again many of my players came to prefer virtual over in person. It makes me sad because I could do stuff like this now without too much effort. What gives?
