Well, this is awkward. I've got good news and bad news. Since it's always better to end on a high note, I'll start with the bad news.
The bad news: As of today (Tuesday, September 18 of the year 2018), there are no events that match your criteria. Absolutely zip. Nada.
The good news: You can change that. You can make the event to end all events. Host your own con, start a local tournament, or share the release date for your latest indie game. Then post about it! We want to know what's going on in the world of gaming, and share it with tons of other people!
