Coming up in July this year is a convention called Anime Midwest. Though it's technically an anime convention there will be gaming-related events there, including an all-day gaming room with scattered tournaments, Ellen McClain (voice of GlaDos from Portal 2) as a special guest hosting some panels, and other things. Here is the official web site. http://www.animemidwest.com/
The typical pre-registration fee before the end of May is $30 for the weekend. If we can get at least 10 people going as a group we can get a 10% discount. I went last year and had a good time. I plan on being there Saturday and Sunday since I'll be working that Friday before. RSVP if you're interested and we can work something out.
