Why does it seem like fewer people do this now? I go into retail stores and find an obliterated label on a cart, and they charge the same price as the good label. I've noticed there is no consideration for condition, at least not so much anymore. On eBay, if the game is not highly valuable or rare, then condition doesn't seem to effect value. The price difference is negligible. Even an Earthbound cart that has been thrashed is only $10 less on eBay than a good label cart.
I hate browsing eBay looking for a cart or disc only copy to complete a case that I have, only to find there is no discount for the incomplete ones. They're basically the same as buying a whole other complete game. So this idea I've always had about keeping cases around because I could save on getting the game only, I'm ready to throw out. Most of the time you can't save anything.
I dunno, I remember a time when condition seemed to matter more. If something was bad, or missing, the value was less. Not so much anymore. Maybe I'm ranting over isolated instances, but it really seems like something's different?
I've noticed that a lot too and it makes me even more cautious when purchasing games. Without a doubt for me, condition, completeness and version type weigh heavily in my purchasing decisions. First and foremost, the game has to be complete as far as CD/DVD based games go. Second consideration is condition. Is the manual beat up with stains on it? Is the disc all scratched up? Nearly as important as that and depending on the games-sometimes
more important-is if it's an original or Greatest Hits version. I've passed up many a PlayStation game because I didn't want the Greatest Hits version with the hideous green label.
I'm particularly picky when it comes to Genesis carts. If I buy a Genesis game, I want it complete in the box with the manual. Why? If I just want to play the game, I have various compilation titles like Sonic's Ultimate Genesis Collection on the PS3. Therefore for me, the condition and completeness from a collectability standpoint is a deciding factor on buying the original carts.
So IMHO, condition & completeness should
absolutely have a strong bearing on the price being asked.
