We aren't adding them because they're sold. We're an abandonware site that deals with abandoned games (which you can't acquire anymore through normal means). A sold game obviously is not an abandoned game, thus uploading it (offering for download) is against site rules.
That doesn't mean we can't add a gamepage for them and link to the place where it is sold. But we still haven't adopted a procedure concerning this kind of updates so we're not going to add them.
I think soon this question will be discussed by the staff. But we still need the review and screens for the future gamepages.
Basically, we can't accept them.
