One thing on my bucket list is to go to the San Diego Comic Con, it is a entertainment convention held each year in San Diego.
I have always wanted to go to E3, the video game convention, that seems really cool as well
What do you think about the New York CC? It's not as old as San Diego or E3, only first held in 2006 but I think it has potential. 
I have never been, but I am a fan of super heroes so I would like to check it out sometime
I think you would like comic conventions then, there are usually a wide variety of panels, focusing on super heroes, there is also great cosplay.
