And god help you if you write games. At some point in my career I'll pass the billion hours of time wasted, at which point I won't know whether to celebrate or cry. Thankfully that day is still 5-10 years off.
For this reason I love Jonathan Blow's attitude about game development.
"Every puzzle in Braid is unique. There is no filler. Braid treats your time and attention as precious. Braid does everything it can to give you a mind-bending experience."
