IE Games (duh!)
Games in general
Rollercoasters (I travel extensively to ride. It's a *very* expensive hobby)
Lifting weights (currently I can bench around 150lbs and deadlift 250lbs. I am old and prone to injury, though).
Perfume (seriously. It's my one girly thing - I love niche and artisan perfumes. This is another very expensive hobby. Sigh.)
