For those not familiar with Gen Con, Wikipedia to the rescue – https://en.wikipedia.org/wiki/Gen_Con
Gen Con is the largest tabletop-game convention in North America by both attendance and number of events. It features traditional pen-and-paper, board, and card games, including role-playing games, miniatures wargames, live action role-playing games, collectible card games, and strategy games. Gen Con also features computer games.
I have never been, but it’s on my Bucket List. It’s scheduled for August 1–4, 2019 this year and is the 52nd anniversary of the convention.
I saw this on YouTube as I was looking for some Gen Con videos – Gen Con Beginners Guide: Advice and Tips – YouTube Video: https://www.youtube.com/watch?v=DVZJ2NiCan8 (around 47:33 minutes long). The advice is usually good for any kind of convention you attend, not just gaming conventions. I have attended mental health conventions and find it’s best to see what’s available and if any seminars or panels repeat in case you have several that you want to attend at the same time.
I have previously posted about CoastCon – Not Too Early to Register for CoastCon42 March 7 – 10, 2019 Biloxi, Mississippi. I have attended a few CoastCon conventions over the years, but none lately. It’s listed on the Wikipedia link and has its own link – https://en.wikipedia.org/wiki/CoastCon. Here’s the direct link to CoastCon‘s website: http://www.coastcon.org/. Next year it will be held March 6 – 8, 2020.
There are a number of gaming conventions around the U. S. and Europe that occur at different times of the year. Here’s a good list – https://en.wikipedia.org/wiki/List_of_gaming_conventions. It’s probably not complete as Wikipedia has some strict guidelines on requirements to be listed. Here are U. S. broken down by regions: https://en.wikipedia.org/wiki/List_of_gaming_conventions#United_States.
For other types of conventions, https://en.wikipedia.org/wiki/List_of_gaming_conventions#See_also. These include anime, comic book, multi-genre, science fiction, and Worldcons.
