I've noticed a big gap in the Epic game session realm when it comes to good tools for enhancing the gameplay. I've seen attempts, but nothing on the level of what it could be.
This past weekend, I was a part of an Epic session and validated a feature set on the app I'm building which resulted in a response of "This is perfect" from everyone that night (including the admins running the Epic).
When it comes to Epics, an easy way to ensure everyone is having fun is to keep the interactivity of all groups high. Secondly, make something positive out of the negative situations. For example, there was a feature we added this weekend to which if someone failed a task, they had to donate X dollars to a charity that was the focus for the event itself. I found this was a really fun way to enhance the game play to make something positive out of negative situations. Basically, people were still having fun rather than getting upset because it resulted in philanthropy. Obviously, anyone could also donate at anytime - but you get the gist. More smiles and laughter than disgruntled faces.
This is one of many examples I see that works really well. Additionally, I'm happy to announce that r/nurl will support Epic game sessions in our upcoming release which you can read about on our blog.
If you are interested in were we are going and the vision to make playing TTRPG easy for everyone (including people on the spectrum or ADHD), you can join the waitlist and get early access to the app before we publicly launch: https://nurl.website
I hope this brought some "inspiration" to all the DM of DM's that love hosting Epic game sessions and happy adventuring!
