Hi Sir Wilfred,
Buffy is correct; we don't have any barriers to events, and anyone can submit events to Gen Con, which we will accommodate if possible, relevant to the convention, logistically feasible, etc. You'll want to review our Event Host Policy for details on how to run events; it hasn't yet been updated for 2019, but will be shortly, and there are not many substantive changes going in.
As for interest, that's really something you'll have to gauge on your own; you can definitely ask here, or on other social media, friends, whoever you think might be interested. Certainly with an event we've never held before, the best thing to do is start small. We can always add seats if need be, and, if there's little to no interest, we can also cancel the event. So, review the EHP, gauge interest around social media, and then email [email protected] if you have any further questions.
