13 Year Old B-Day

I need some ideas for my b-day party coming up oct.17/08 and I was thinking of first going to the movies to break the ice then coming back to my house and the girls have a singing competition and the boys have a video game competition (whoevergets the most kills on Halo3 ;which rocks!; win. And then the winners have a dance off... I wanted to know if any of this sounds lame so can someone plzzzz help me? my parents can`t think of anything and neither can my soon-to-be 11 year old brother!
