What should I do on my 14 hour plane ride?

I am a 16 year old, have an iPad 2, an Android Phone, and tons of music.. I am pretty sure I am not gonna sleep because its very hard for me to sleep normally and i know im gonna be too excited on the plane. I also will not read. What can i do with the iPad 2 that will keep me entertained for 14 hours. I already download like 5 movies on the iPad and i need some really really time consuming yet very entertaining and fun games for the iPad 2.. Preferably free games. I beat Age of Darkness in like 4 hours nonstop i loved that game. Thannnnnkkkkkssss
