I took a gamble, an inexpensive one with a Goodwill store recently. Still waiting on the package. They sell everything with generic descriptions and stock images.
I know, I know, never buy a game with a stock image.
But, when something pops up for a 1/3rd the average price from any seller and claims to be "very good" condition, it's hard to say no and opt for a more expensive listing with a picture.
I don't know how these GW stores operate, they seem to have their own idea of what condition is. Which is against eBay's policy. eBay defines "very good" as having the artwork and liner notes without much wear and tear. These GW stores on the other hand make no mention of completeness, but as far as I know are bound to the same policy as everyone else, or should be. I'm just hoping I get lucky enough to receive a complete game (PS1 game) that isn't too trashed up. I've bought a music CD from a GW seller, it turned out complete but kind of worse for the wear.
I know there are many sellers who disagree with that policy, who think as long as the disc or cart is good looking, it should be above acceptable. I disagree there, and side with eBay on that. Acceptable is the condition of an incomplete game, imo. Even if the game looks mint. In the description a seller can brag about cart or disc condition until their heart is content.
