Collecting Critics vs. Duke !!

I always get critics who tell me that its pointless to collect Xbox "stuff" . That it will never mature in value and that it doesn't have that same feeling as a nintendo item. I never believed that and I save anything I can get my hands on with that little green logo.

Here is a perfect example: The Original Xbox 1 " Duke" Controller.
Current eBay price: $102

Holy crap Batman ! That is insane, even as a collector i'm shocked. I mean you can pick up a mint NES controller for less then half that price and it is for a vintage system. But then again how can I say im shocked, I once sold a X-Men Legends (Xbox 1) Strategy guide on ebay for 125$ .
