I picked up a Wii game today that at first glance appears to be this one:
http://vgcollect.com/item/21537But the one I have has a different item number: RVL P RLFE
At first glance it doesn't appear that it is any different than the one already in the database.
I got this used, but did a little research and found that the particular game I have (with this item number) is from this accessory bundle:
http://assets.dreamgear.net/manuals/DGWII-3160.pdfdreamGear 3 in 1 bundle. The reason I ask about adding it to the database is because I don't see a clear way to find it. For example, searching for item numbers do not work. The advanced search is only for product title and barcode. This variant game has the same barcode as the regular release. Also, product records themselves are not really searchable, so if someone were to search for this game they wouldn't get 2 results. An example of this is if you search for Altered Beast, you don't see the appropriate Sega Genesis console as a search result.
Another issue is that you cannot see what a particular item includes unless you add it to your collection. So for the regular Altered Beast game, you can't see that it is case, manual, cart, insert, etc.
