Still love mine (pro). I think judging it by the market place ads is not a good idea. Theirs just as many Trons going up for sale and we would agree Tron isn't a bad game.
I don't think their are to many people on this forum that keep a pin forever. I see more people as those wanting to keep things moving around thus why you see so many pins for sale.
There are just so many awesome games out right now it's hard to keep them all for financial and space reasons. I want a ST, MMr and the new Mustang pin. Space and $$$ don't allow me to buy them all though. I may sell something but it wont be AC/DC, AV, TF or BOP
