Sometimes this is the result of an original edition released in limited release and a follow-up mainstream release, but both games contain basically the same bits. (ex: Reef encounter.)
Sometimes the original release is different from follow-up releases because they contain extra functionality (ex: carcassone vs. carcassonne w/ river, vs carcassone big box)
The homepage for a game would contain all pictures, info and forum conversations about the base game and all of the various specific editions. It would also prominently feature a list of editions so a user can drill into a specific edition and see info/pictures that pertain to that edition.
Likewise, a user who owns a game can specify their edition if they want, or they could mark that they simply own the game without specifying a specific edition. This would also allow users to simply mark any version of the game as "wanted", or, they could find a specific edition that they want and mark only that edition as wanted.
Hierarchy of games, expansions underneath main game:
It is slightly odd how expansions to a game like Ticket To ride or Carcassonne are lsited as separate games. The site would be much easier to use, if the expansions were tagged as children of the base game. (...and likely easier to monetize with advertising.) Then, it will become easy to see the expansions as they relate to the basic game.
A reworking of the expansions is on the to do list, I believe. For now you can of course re-write the game description and add in the expansions, etc.
Inns & Cathedrals

I've actually been working on just such a project, especially for the games that aren't part of a series. I'm putting links in the description of the games showing how they interrelate. Each game that has expanisions, I'm putting in an Expanded by: link, and each game that is an expansion gets a Expands: link. Additionally, games that are re-printings, re-developments, or related to another game get Re-implements and Re-implemented by: tags.
