There a lot of different styles of DMing in D&D and other roleplaying games.

You can wing it and come to each session with very little prepared.

You can come up with the adventure for each session in the week before.

You can also do what I do, make up the entire campaign before starting it.

Between each session I have almost no creative work to do for D&D. My campaign has been running for close to three years now and I’ve only had to design one adventure out of about a dozen since then.

It’s nice. I don’t need to spend extra time on the game for me and my friends to have a lot of fun.

I have started to run into a few issues though.

When I wrote the campaign I imagined my group would still manage to meet in person.

That proved to be horribly wrong. We have in person sessions about once a year now.

When I drew all my maps they looked like the one pictured above. I’d make them on a piece of yellow-green graph paper.

When they reached a room I’d draw with a wet-erase marker on a battle mat I brought to each session.

When the players defeated the monsters in one room I’d erase and draw the next room.

Dry erasing was easy, but creating good maps in our current system is a little difficult.

My group now plays over the internet using an internet browser program called Roll20.

Roll20 is really great. It has everything a tabletop has. You can even turn on a feature to see your dice roll across the table.

However, I can’t just grab a pen and draw on my monitor as easily as I draw on the battle mat used previously.

I suppose I could do that if I was used to creating digital images, but I’m not.

Instead I’ve taken to making lame looking maps or using a cool mapping software piece called GridMapper.

GridMapper is extremely simple. You pretty much just click to change stuff.

I can easily build maps in GridMapper. They don’t look amazing because it doesn’t come with preset images like trees and stuff, but they’re functional just like my dry erase mat.

GridMapper has one issue, it has a maximum image size. Easy to get around though, I just make two images and glue them together for really big rooms.

I’m slowly converting all my old pencil maps into GridMapper maps for Roll20 now.

That’s it for now!

Welcome to the GoCorral website! I’m Isaac Shaker and this is a place for me to write about D&D and occasionally other topics. I host a podcast called Setting the Stage that interviews different DMs about their campaigns. I’m currently focused on completing the Cimmeria campaign setting and turning it into a book.

81 – Biopunk 2287 RPG (Seiya and Synesthesia Synthetica) Setting the Stage, Campaigns for D&D and Other RPGs

Seiya tells us about his TTRPG system and setting, Synesthesia Synthetica (SNS). SNS is a biopunk game adjacent to the cyberpunk and steampunk genres. After an asteroid induced climate disaster, Earth has rebuilt itself using bio-technology instead of the metal based tech that surrounds us in the real world. Genetically modified humans have split into distinct species and mutant horrors prowl the wastes outside civilization. The rich rule from their space stations up above but resistance is growing in the streets below.During the episode we discussed a piece of art that Seiya had made for the game. A picture of that bio-tank is available for you to look at.At the moment, Synesthesia Synthetica is available for free as an early access game on itch.io and DriveThruRPG.If you want to learn more or find a group to play with, you can do that on the Synesthesia Synthetica Discord.Remember to nominate your favorite TTRPG shows/creators/things for the 2026 CRIT Awards!Check out the Setting the Stage website!Want to be on the show?
