Nice ideas in here! 
My (current) personal to-do list:
- Fly (just done that in NDs, often didn’t work very well)
- Flying variation: Fly beeing Ken / Joe from Gatchaman
- Fly a Light Jet (-> Tron Legacy)
- Swim with dolphins
- Meet Sonic the Hedgehog & Tails (yes, I am a BIG fan of the Sonic franchise
) / Race Sonic - and Win! 
/ Clobber Eggmans Robots
