Supported Virtual Tabletops (VTT)

AetherCon we support two VTTs:

  • com
  • Google Hangouts


For GMs new to online RPGing and Roll20, check out the Tabletop Tutorial here. Still need

help? We will also be offering live tutorials with experienced hands who can walk you through

setting up and running your game. Contact our tutors at

Google Hangouts

Setting up a Google Hangout is super easy once you have a Google account. There are several

ways to do it, but perhaps the simplest is to create a calendar item on Google Calendar. Follow

these steps:


  1. Create a Google account or login to your existing account.
  2. Go to Google Calendar at
  3. Click the red “Create” button on the left.
  4. Provide a title for your Calendar item (this is really just for your eyes).
  5. Set the date, time, and time zone.
  • Use your first choice’s date and time here.
  • If your first choice is unavailable, we will let you know. You can then come back and

adjust the calendar item. However, this is strictly optional, as the date on the

Hangout doesn’t affect the link.

  1. Click the “Add Video Call” text link; this is the action that establishes a URL for your


  1. Provide an optional description; again, this calendar info, apart from the Hangout link, is

just for your eyes.

  1. Do not add any guests.
  2. Click the red “Save” button at the top; you will be returned to the main Calendar view.
  3. Find the calendar event you just create and click to edit it.
  4. Right-click the “Join Video Call” text link, and copy the URL.
  5. This is the URL you use on your form. Don’t lose it!


Note: Hangout URLs are permanent and can be used for multiple, successive Hangouts. If you

are running ten games, at different times, you really only need the one Hangout URL.


GM Registration Form


You can find the GM Registration Form here.


This online form must be filled out for each event you will be running. It provides our system

with the details of each game you’ll be running, including a description, and the virtual

tabletop (VTT) link to your session.


Organized Play

Remember if you want to run Cthulhu Cult of Chaos, D&D Adventurers League, Pathfinder

Society, or Starfinder Society you need to register by using the e-mails below and *not* the

form above:


  • Cthulhu Cult of Chaos:
  • D&D Adventurers League:
  • Pathfinder Society:
  • Starfinder Society:


Deciding to Run a Game at AetherCon


We are assuming you have a lot of experience with role playing and/or table top games. But

you may be new to the online experience of gaming with others over computers using virtual

tabletops. Some of our online players have remarked that online play can be similar in

enjoyment to in-person games. Others felt that online play can allow the GM and players to

focus more on the story compared to meeting in person.


Having to carry around loads of books, dice, pawns, etc… PHEW! Using online tools can be

easier once you understand how to use the tools available. And then sometimes it’s fun to

teach your friends something new by using tools like Google Hangouts or Roll20.


Registering your Game at AetherCon



We welcome all systems at AetherCon from the Industry Giants to the smallest in Indie Press. However remember to keep in mind that lesser known games and homebrews do not have

the exposure of better known systems. For that reason, taking full advantage of this document

is recommended.


If your first thought is “I’ve always wanted to try running this game but couldn’t find any players…”, that should tell you that you probably need to put in the extra mile to attract the necessary traffic.




Put up a decent descriptor. If your descriptor reads “Dungeon crawl for five players,” expect

potential sign ups to treat your game with the same amount of enthusiasm you are.


For Open Games (which includes Publisher Run Games but not Organized Play), make sure you

accentuate the fact that anyone playing in your game can win the Open Gaming Bundle by

including the phrase “Players eligible for Open Gaming Bundle!” after your descriptor.


If you plan to beta-test an unreleased system make sure you mention that. There are plenty of players out there that enjoy playtesting. Make sure they know you’re looking for them. Maybe bring a couple of your own beta-testers along for the ride and turn your game into an event by featuring them.


After Registering


After you register your event, it will be important to start developing the virtual tabletop (VTT)

your game is running on to increase your chances at a full table. Here are some ideas to help.


Your Virtual Tabletop


Populate your Roll20 campaign with a cover sheet. If folks sign up for your game and see a

blank white page they may wonder just how committed you are to running it and ask

themselves why they should be more committed than you are. We’ve made a media kit

especially for GMs. You can find it here.


In the case of homebrew games, the RPG rules or rules changes from the system you are

basing your homebrew on should also be plainly spelled out in the journal section of Roll20 for

player viewing prior to Player Pre-Registration starting.


A Note to Publishers and Beta-Testers


Providing a two to three page PDF that either explains how to roll a character or is short overview of your setting for our RPG Sneak Peek Collection can help put people at your table. Those we receive will be linked to that game entry on the event schedule.


For Roll20, Dynamic Character Sheets (ones that remove the math for the player who clicks on the appropriate dice icon in the Character Sheet to have it calculate the variables and produce a result) are essential, especially for games with a heavy math content. Investing the effort to ensure you have these available will benefit your game at AetherCon and make your game easier for a GM to select going forward.


Similarly, building out your game table (adding the maps and NPCs) once can benefit you for not only AetherCon but for other online events you participate in further on down the calendar.


As with anything, using Social Media to get the word out about your participation in AetherCon always helps. Make sure your supporters know when your itinerary be it games you are running, webcasts you will be a part of, when you will be in your booth at Baublebrook’s Bazaar, or even bartending in The Wandering Toad. Adding ‘#AetherCon 15-17/11/2019’ to your Twitter name will help make sure your Twitter followers know where you will be during the festivities.


Like Social Media, your website can also help raise awareness. Make sure you put our logo in a place that will be easily seen and backlink it to our website. Putting your itinerary here as well can also go a long way.


The Online RPG Community is expanding as more gamers grow up in a digital world. Putting in time here will help place you in the path of the next wave of RPGers.


Character Creation


  • We highly suggest that you supply characters for your players if you are running a non-Publisher Open Game. If you are a Publisher we suggest you either supply characters, or if you have a new system, perhaps make the characters at the table with the players and use a

shorter scenario.

  • If you are providing characters for the players we suggest creating an extra one for every two characters the scenario requires so as to give the players more options when it comes to

selecting what kind of character they would like to play. Also, when making the characters,

write a couple of sentences. Who are they? Why are they? Nothing fancy, just two or three


  • We also suggest that the characters be viewable in Roll20 by the players prior to Player Pre-

Registration starting.

  • Start a Roll20 Forum Chat where your players can touch base with you prior to the big day. It

will provide a way for them to ask questions about things they are uncertain about and help

your session run smoother so that come game time you are playing and not explaining.


Get the Word Out!


Simply put: Advertise on Social Media! You know who your demographic is likely to be more

than we do. Get the word out. AetherCon will always do its part to promote games on its

schedule, but your effort here only improves the chances for a great time.


Remember: You will get out of your game what you put into it.


GM Table Count

Remember, you and your players are eligible for prizes! But we can’t get their loot to

them if we can’t contact them. It’s imperative that you fill out the GM Table Count

Form during or immediately after each game.


You can find the GM Table Count Form here.

The form asks for your scenario’s name, when it was played, how many players attended, and

the contact info for your players.


Final Thoughts


In closing, remember to have fun! 🙂

And don’t forget to keep checking back with us as we roll out all of the other events happening

during AetherCon Weekend, November 15-17, 2019!
