Can you give me some PAL games you tried to add that were imported as the NTSC version?  I can't replicate this in my tests, but if you can give me complete examples I can look into those and fix them.

We have it listed here:

This is a PAL only release.  I can add it when we add a full list of 3DS games to the site.

I've linked all the PS1, PS2, Gameboy, Gameboy Color, and Gamecube consoles with Gamestop listings that I could find.  Prices should start showing up in the next 2 days or so.

Add it now:

We aren't tracking PAL 3DS games yet, but when we do add them I'll be sure to add these titles too.

We have the US versions of both:

We don't track PAL hardware at this time, just the games so I can't add the PAL versions.  I'll leave this open to see how popular that is with users.

You can see another user's collection if they share it with you.  But we do not provide any list of user's collections that you can browse and find other users?

Is that what you are referring to?

I've added this now.
