Alright, that makes sense. That way you can still pull down the data from Giant Bomb but allow the Grouvee data to show instead. I can see it being tricky because you are dealing with more than one straight compare like the box art. When you get to releases or platforms, that could be x number of records.
Someone mentioned it above, but cleaning up the platforms list would be cool. I hate how Giant Bomb has stuff like Playstation 3 and Playstation 3 (Network). It is really the same thing. Though it does tie into my email about tracking physical versus digital copies.
