What's the deal with the trend of the local retro game stores that have been popping up all over the place now? The ones locally here are all the same, they price everything with at least a 10% markup from the highest sold price on eBay, yet they still do decent business? Who are the people that are buying games from these places, is it the casual gamers that have bought into the hype of the retro gaming fad, and just get caught up in buying stuff on impulse?

For example this place: http://www.yelp.com/biz/video-games-new-york-new-york. I've seen people astonished by the videos of this store on Facebook, but the big secret is that the reason they have so much cool stuff in stock is because it's priced way way way above what they are actually work. The store only stays in business thanks to trust fund hipsters that don't care about paying $15 for a copy of SMB / Duckhunt and $120 for an NES to play it on.
