I've been to SDCC and smaller comic conventions, but I've never been to a true gaming convention like #Genacon or #GameHoleCon. I assume there are differences depending on the specific convention. Are there any good websites/resources/etc. other than scanning social media posts about what to expect from different cons? If anyone wants to share a favorite (and what they like about it), I love to know more. I've been playing RPGs since the 80s and would like to try a few cons.
