I dunno, early Id Software seems like a good example. Personally, I think it directly relates to having people do something their passionate about. 20, 40, 80 hours...doesn't matter, getting a group of programmers excited and passionate about getting a taxi from point A to point B is probably unlikely. But get a group of people who grew up playing D&D and tell them to make it real...
