I'm going all four days. Games morning, noon and night. A few of the cool things that I've signed up for:
OriginsCrawl 2004 - Every year, Pandahead Games runs an XCrawl at Origins, and the winners of the crawl will have their characters featured in a new product next year. Often the writers run the games so you get to meet and talk with them as well. Lots of fun!
7th Sea games - The old roll and keep system. I played in an adventure last year written and run by Patrick Parrish, which was called A Fistful of Guilders. I had so much fun, that I just had to sign up again this year.
D&D with Jonathon Tweet - Yeah! I got into this game early.
In addition, I'm also very happy that Green ROnin will be there, because I'd like to give them some money. I need to catch up on my Mutants & Masterminds books. I hear Steve Kenson will be there as well, and I may be geeky and have him sign my Mutants & Masterminds and Freedom City books. I for one am really looking forward to Origins this year.
