Mini Games That Were As Good (If Not Better) Than The Real Game They Appeared On.
This topic is spinning out of a five minute conversation I just had with someone about how awesome Sega Swirl was. My memory is a bit hazy, I can't remember if it showed up in a demo disc first or if it was part of the web browser from the beginning. But it was addicting as hell and was one of the few games my chick would play. It was actually annoying how much she'd play it.
So that got me thinking about the topic and what games would fit. Geometry Wars and Portal immediately sprang to mind. I definitely liked Tiny Phalanx more than Zero Divide.
Were there any games you'd pop in more to play the side stuff than the actual game? Shenmue...
