AnimeCons.com: Convention Schedule has dates and links to official sites for you as well. And to answer your question about if anyone does watch anime or play video games, yes I do ^_^
Oh and I recomend Otakon. Biggest anime/gaming convention on the east coast. It is in Baltimore maryland but 23,000 otaku in one city is soo much fun. It's a true experience.
