I have this version. But I don't even know how much it's worth. Disc is practically brand new with original case and manual.
Man I had to use magnification to see the numbers on it. I knew it was this version though before lookin at it since I got it right when it came out. It says "For Display Only" on it, funny that EB Games gave me the display case, wot.
I found it on ebay here. It is $16.98 + $3.77 shipping for a total of $20.75. It looks like it is in pretty good condition as well, but I like hearing someone say it. So, I'd be willing to pay you $25 for it, which should include shipping.
