The perfect orders in the customer page galleries don't need to be organized by game. If they were to be organized, the staff members and other users would be pressured to check the gallery every time a perfect order is added to the page to make sure that the image was added in the right location. They certainly don't want to waste their time doing that when there are other more important things that can be done here. Not only that, but the majority of editors wouldn't know and/or care about this organization format, thus making it very difficult to keep the galleries organized constantly.
Oh....ok.. Everytime I wanted to add an image of a perfect order for a customer in STG, since it wasn't organized, I had to scroll through the entire gallery section to see if there already was an image for that game... So I thought it would be better if it was organized by game, making it easier to add images for certain games. I am willing to organize the perfect order section for the other customers, though, so if yoiu feel it would be easier to find and add images, I can continue with it.
