So I like the idea that the new submit form looks for the game you are adding to cut down on the duplicates. But there is a problem with this and it relates to how searching works. Let me show some examples.
Searching for NHL 2000 shows the PC and PS releases:
http://vgcollect.com/search/nhl+2000It however, does NOT show NHL Championship 2000. In fact, NHL Championship 2000 for PS does already exist in the database (incorrectly) as Fox Sports NHL Championship 2000.
http://vgcollect.com/search/nhl+championship+2000Of course you'll notice a PC version in those results, that's because I just added it. Here is where the problem with the search on adding the items come in. When I added NHL Championship 2000 (for PC) it did a search for the game to make sure there you aren't adding a duplicate. The problem is that it did NOT find the existing Playstation one, which you'd figure it would since it finds it with the manual search.
I won't edit the incorrectly named Playstation entry as it may invalidate my report. To be specific, the product should be named the way I did in the PC version, where the "Fox Sports" part is the secondary name. And no, I don't know why the PC version has a Sony part number.
