Impromptu Con FAQ
Discord Invite: https://discord.gg/phXSCzd7Sj
What is Impromptu Con?
The better question– what is impromptu? Impromptu is something done without being planned, organized, or rehearsed. As such, Impromptu Con is a very impact-light, easygoing, and free online gaming convention that celebrates all things Chaosium!
We held the first Impromptu Con back in early 2021 during the Pandemic when everyone was locked in at home. It was a lot of fun, well attended, and left everyone with a happy glow, so we held several more Impromptu Cons during those challenging times
Impromptu Con is hosted exclusively on the Chaosium Discord here.
What can I expect from Impromptu Con?
Chaosium games will be running the entire weekend from volunteer GMs. Chaosium staff may stop by and host panels and/or workshops. There will be giveaways. We may host a couple live Actual Plays. You gotta be there to find out!
Will you use a convention management software like TabletopEvents?
No. That sounds like planning. We try to minimize that here at Impromptu Con.
Will there be a schedule of events?
Not really. Panels, workshops, and actual plays will be scheduled and announced ahead of time.
Chaosium staff will stop by throughout the weekend. They may hop into a video chat, they may lurk and stalk in content channels, they may host surprise text AMAs. You never know with Impromptu Con.
Available games will be posted in the Looking for Group category in our Discord. You are welcome to sign up for events at your leisure.
What timezone will this convention be held in?
Chaosium is a small global company. We work around the clock. Our mod crew is global. They monitor around the clock. Our fanbase is global. You play around the clock.
As such, there is no designated time zone for Impromptu Con. For mod ease, we’ll be posting times in Eastern.
Swing by! You’ll never know when a game submission fits your timezone, or when a staff member from Ann Arbor, London, Melbourne, or somewhere else in the world may stop by and hang out!
What are the server rules?
We’re so glad that you asked! Visit the rules channel to review the official Discord server rules. By joining the server and participating in Impromptu Con, you are responsible for adhering to these rules and expectations.
How do I get the Impromptu Role? Why should I get it?
Visit roles and assign yourself the Impromptu Con role. We’ll ping this tag specifically for items related to your Impromptu Con experience (giveaways, events, FYIs, etc.). That way you can downsize the other aspects of the server that may not be related to your convention experience.
How and when may I submit games?
You can submit games now. Schedule your games at your convenience. Our only requirements are:
- The content must be Chaosium IP.
- You must list the content in the Looking for Group category in our Discord, and use the “Impromptu Con” tag.
- The game must be free to play.
“Can I run homebrew/unpublished/modified/etc?”
Yes! As long as you’re running a Chaosium system. Just make sure to set expectations like you would for any game regarding setting, system, and tone in the event description!
“Can I list my game on Roll20/QuestPortal/other site?”
Yes! As long as the game is also listed in #looking-for-group with the event tag.
“Can I run a paid game as part of Impromptu Con?”
No, all events for Impromptu Con are free to attend.
Helpful hints?
- Use this universal timezone converter when posting and scheduling your game
- Use the “Impromptu Con” role tag when spinning up your event
- Here is a free and shared dice bot roller for your convenience
Where may I run my games?
Run on the platform of your choosing (Zoom, your own Discord, your favorite VTT, whatever works for you!)
Note: The Chaosium server is not available for running sessions. We will not be providing voice/text channels nor dice bots.
Are games run at Impromptu Con “Cult of Chaos” friendly?
Yes! Approved Cult of Chaos GMs will be awarded store credit for running games from the Cult of Chaos Library during Impromptu Con.
Are you curious how you can get paid to run Chaosium games at cons? Visit the Cult of Chaos Gamemaster Program webpage for more information and eligible content.
May I submit a panel or workshop?
At the moment, panels and workshops are for Chaosium staff and those who we directly invite. Check back during the next Impromptu Con for additional opportunities.
I have additional questions!
You may open up a help ticket on the Discord server here or post your question in the Impromptu Con channel. You may also email Bridgett at Bridgett@chaosium.com
