Found user necron99 who's basically creating new "Canadian release" entries for almost every game in their PS3 library. This raises the question: are the canadian releases any different than the US counterparts? If so how can we prove it? If it's just a product number difference (this is the case with modern nintendo games too) does that grant the game it's own entry?
The topic of inconsistent product numbers has been brought up before in THIS thread.
They are different because of their packaging. They are bilingual. If there is a case where, say, a Canadian release's contents are not unique, then it should be noted within the description as to that fact. Same would go for the euro DS games as well. In some cases, not only the product number is different but sometimes the artwork is different. This is true of sports games, where a "fellow countryman" will make the foreign release cover rather than who was on the US version.
That user seems to have added the entries correctly (notably the artwork appears to be bilingual) however the style guide says you should use [CA] instead of (Canadian release) in the title.
