it is rather curious.
Even the few local copies that's still in store (Radio Shack, EB, and independent firms) are still marked at premium...
A NEW game sells for around $60CDN, and the SFC3 copies on sale locally are still labelled in the neighborhoos of $45~50 CDN.
As many have observed OP is MUCH MUCH cheaper (the ones in store are going for around 10~15.) But that's not the most curious thing, even other older or similar aged "big brand" games have come down in price. (Age of Mythology is only 6 month older, but is selling at $30ish... Heck I've seen Doom 3 priced cheaper than 45...)
Something is keeping the price of SFC3 higher than usual in terms of the length after release. I wonder what could it be... A collector's item perhaps? (being the last trek game actvi did)
