same here, I went pretty much SMS, GG, Genesis as nintendo stuff is just outrageous in price especially since almost everything out there is a loose cart. I mean the mark up on popular and most widespread games is crazy. I would like to own a copy of contra and super metroid but not at 30+ bucks. For $30 bucks i could get 3 or 4 CIB genesis games.
I think a lot of the problem is resellers and people with a HUGE nostalgia footprint on what they have. New retro gaming stores are popping up left and right around here, they come up with the most amazing finds and then turn it around and sell it for big money (or try to) and those with the huge nostalgia problem see those prices and also they just feel that because of their attachment that it is worth huge money. At the same time there are those that just don't know and you see them selling stuff at their garage sale for stupid money. I see that a lot.
obviously there must be a lot of people out there paying the money because the prices don't seem to be dropping.
though, I would like to hope for a huge crash....
