I was discussing with Jackal a point of what region should be assigned to entries.
I believe country of manufacturing is a bad way to assign region, example:
https://www.ebay.es/itm/274285642923
"Assembled in Germany" manufactured in Germany, yet Distributed only in Spain. Should this be Germany or Spain? I would think the answer is simple - Spain.
There are countless other examples of games being manufactured in one location, but distributed specifically in others, and they are correctly given the Distribution region.

An example of contention:
http://redump.org/disc/72412/
This is a USA-exclusive packaging, it was never released in Europe this way - period. Since the disc is region free it likely matches content with the other regional packages. So it would make sense to me mark region as USA (or even possibly World if we want to get ahead of ourselves assume all regions match).
However it's marked as Europe? Why? Because it was manufactured there? If manufacturing was the deciding factor of region, we should mark all PS2 discs as "Austria" region, as that's where they're made. "Who Wants to Be a Millionaire: Irish Edition" region? It should be Austria of course (according to this bad logic).
I rest my case. Jackal asked me to post this for your feedback - what is the rule for regions, where they're made or where they're distributed?
