I thought I'd ask here although it's a big off-topic, I figured at least some would have overlapping interests with me.
My wife and I wanted to go to a Comicon type event but I don't even know where to start looking. We are very into retro video games (we don't own any modern systems), sci fi (star wars/star trek) but not so much comics, so we were trying to figure out if there is something that encapsulates more than one of these things in the midwest area (we're in Chicago) or if Comicon would be of interest to us (knowing like nothing about comics). Googling gave me a bunch of obscure Chicago events that I'm not sure would even be worth going to...
