For example, I don't really like the DC copy of Maken X or Unreal Tournament I have (just not really a fan of FPSs). But, if I sold either on ebay or amazon, I probably wouldn't get more than $4 for it. Take out the commission fees for using those websites and I'll be getting paid $2 or $3 to take an hour out of my day and put it in a package, bring it to the post office, etc. At that rate, I think I would get more than $2 worth of enjoyment out of just keeping it around and looking at the manual cover in my pile of games from time to time
