Yeah, no. Chicago is too far.
If it were some place like LA, or New York, I wouldn't mind at all cause Id enjoy to go there.
But Chicago?
I have no plans to visit that place..
Also, a convention for just Blockland? We'd only have to rent a local gym for that.
It would be like an extremely autistic school dance...
Just get a booth at an already existing, already popular, video game convention.
