Jetpack Joyride is a free PSN game that is good for a quick thrill. You pilot a jetpack, to go up you hold the button to go down you release it. Basically you just go right as long as you can. There is some gameplay diversity in the form of other quirky / crazy modes of transportation and because I don’t have any other quick thrill game on PS3 I keep going back to it. I’d justify $5 for it.
