Help !!!

Hi Iam turning 13 in July I have allways had big theme parties in the past, but i didnt know if I should have another one again this year,and if I did what would the theme be ??
I was wondering If you had any ideas about really fun games to play or what to do from your experiance.
I usualy have my b-days @ my house but if there is another place that u think is a heck of a lot of fun , please let me know !!!!!!!!
