For one of my friend's 14th birthday a few years back, she had a game show themed party. It'll go down in history as the best birthday party I've ever been to. We played The Mole, Who Wants To Be A Millionaire (Disney version!), Survivor [well, it was really a series of team "challanges" (for example, we made pizzas for dinner but we were divided into 2 teams and her mother hid the sauce, pans, dough, toppings, etc. around the kitchen and we raced to find things and make the food which was beyond fun and we've done it every year since [even if it's not her birthday!])], etc. It was a lot of fun.
