Harrison also mentioned that GPS functionality will soon come on board, noting that, “Although geocaching is as underground as it gets, who can't see potential?”.Geocaching isn't exactly an underground activity, though admittedly it has been called "the most popular outdoor activity no one knows about." There have been literally thousands of articles written about the activity, radio interviews with geocachers, and it's even listed as one of the top "treasures" on a repeating show on the Discovery Channel. So what does Harrison, the president of Sony Computer Entertainment's Worldwide Studios mean exactly?
My interpretation is that if it isn't mainstream it is underground, at least for the larger game development companies. Geocaching doesn't fit well into any of the standard genres like first person shooters, adventure games, sport or activities like golf or kayaking. It combines technology and the outdoors and is hard to put your finger on.
It does have a worldwide following but no real statistics have been reported on how popular it really is. Perhaps if that information was available it would change some minds on the subject. Or maybe it is still underground. I kind of like it that way.
