GenCon is my favorite. I've been going for the past six years. Plus, it's only an hour away from where I live. They have a great bunch of writers that attend and their seminars are fantastic. There's plenty of gaming. I get both my writing and gaming fixes!

I went to Archon last year and didn't enjoy it as much. They have some good writers that attend, but I liked the seminars better at GenCon. I've been to other smaller conventions, but GenCon still holds the number one spot with me.
