Last year was our first Star Wars themed show, since it fell on Star Wars Day itself. We each took on a Star Wars character and tried to play that character through the show. I was Yoda, but at one point I did a scene as Luke that was well received, so this year I played Luke all the way through the show (yup, with a wig). And we made the show even bigger with light sabers, cardboard cutouts, and a Darth Vader helmet.
Our MC, Julianne, was also the one who organized the show. She made sure all of the games were Star Wars themed, and it was up to the players to keep in character. We played about 15 games by the end of the night.
Probably my favorite game involved a setup where Julianne and I were at the registration desk at Comic-Con. Before the show, the audience filled out suggestion cards with the names of characters from any fan supported universe (comics, TV, movies, etc), and they were all placed in a hat. During the game, a player would draw a suggestion from the hat, and then walk on stage as a cosplayer in character. We had to guess who they were. We did 20 walk-ons representing 30 characters (several walk-ons involved two characters). We only missed guessing two characters.
I thought the show was very good and at some point I'll edit the video I recorded and post a link to the show here.
