HeroesCon is different than many other cons out there because it still focuses mainly on the comic books and not the latest movie, tv series, or video game. All of the local stores come out so you get to see a lot of familiar faces at the booths. There are a plethora of artists and writers who get tables so you can watch them work and get to meet them. Looking for merch? This con has plenty of merch booths.
My favorite parts of this con are the cosplay and discovering local independent businesses (Like HandmadeStuffs, HeroSquares, TeeMinus24, etc.). The attendees are a great variety of demographics. People are very amicable and have no trouble striking up conversations with strangers. Cosplayers are very gracious and willing to strike a pose or chat.
I've been going to HeroesCon for well over 5 years now and it keeps getting better without losing the aesthetic that keeps packing people in.
Tip: don't want a convention lunch? You're already in uptown so take a walk to any number of restaurants. Don't want to take a long break? Fuel Pizza has a location directly across from the main entrance.
Tip: Heroes Aren't Hard to Find (HeroesOnline) are on Twitter and Facebook. Follow them to get updates on the Con, who will be attending, and ticket info.
