I'm not sure if anyone knows the answer to these questions, but I'd take an "educated" guess. Firstly, I was digging through the hundreds of copies of Madden 2005 I got the other day (at the store I work at) and I noticed several of them had a weird ink issue - basically it looked like the word "Madden" had been "ghosted" on the bottom of the spine, so, basically it said Madden 2005 and then it had it again very faintly. I know misprints of stamps have a high value, I was just wondering whether misprinted game covers have a high value. In the case of this, I don't think it would be major enough even if misprinted covers were more valuable - but in general, are they? I mean, I doubt a run of Final Fantasy XII would ever make it by quality control saying, "Fnal Fantasy XII" or something... but if it did? Are there any known cases of this?
Second. Does anyone have any idea whether the new limited editions of Mortal Kombat: Deception will increase in value or whether they're likely to be "fools gold" like the "limited edition" golden N64 cartridges for The Legend of Zelda: Ocarina of Time - which are so easy to find you can still trip over stacks of them. For anyone who doesn't know - they're releasing MK: Deception for Xbox with four different "Kollector" covers and I think the PS2 version has the same (or maybe just one collector's edition). I'm a big MK fan, so I'm not just out to snap these up in droves so I can post them on Ebay in a couple of years. That said, I really don't *have* the money to spend say $200 on one game if I could pick them up in a few years - I don't want to miss my chance and have to pay $100 each.
Phew, that was long.
