[quote name='rawrker']See thats what I don't agree with in regards with GS. If they deduct the TIV of a game if its not complete, than they should deduct the sell value of the game if it isn't complete as well. As we all know they don't do that. Around where I live we have 4 gamestops all riddled with incomplete games. Now if I buy one, and resell it later and they knock them for not having it complete thats really stupid imo.[/QUOTE]
Actually, it's not. It makes sense from a business standpoint.
They don't discount incomplete/damaged cases/instructions because it would lead to vandalism and inconsistency. Say you want a used copy of some hot new game, but you don't want to pay full price. You damage the manual (or chuck it), damage the case, etc and demand a discount. And how much of a discount do you get? Is it a sliding scale? Imagine the arguments that would lead to. This is the same reason most major retailers won't discount for damaged packaging any more--customers started damaging it on purpose to save a few bucks.
As for not offering as much for incomplete games, that is because they aren't worth as much. Price isn't the only factor. Shelf appeal is part of the equation. Games with cases/manuals move faster. For example, I will almost never buy a used game unless it's complete and in very good condition. That's just my preference. So an incomplete game in a generic case and a complete one may have the same price sticker, but one is garbage to me while the other is not. And plenty of other people feel the same way. So Gamestop prices accordingly.
