This site has a tag for games that get relisted, but it really needs one for games that got remastered as well. It's a bit misleading to say a game is gone when you can still buy the GOTY version.

Really, it would be nice if every listing had a 1 or 2 word tag that summarized the reason for the de-listing.

Publisher Closed

Servers Shut Down

Remastered

License Expired

TOS Violation

That sort of thing.
