That game was only released in Japan and we don't track prices for Japanese Virtual Boy games yet.

I've never heard of this item before.  Where did you get this photo?  I'd love to hear more about it.  

Thanks for the suggestion.  Do they have a collection export tool?  If so you can probably do this already using their export and then our import tool.

You would export the collection and then paste the collection info into this tool and we would import everything and tell you which lines we couldn't match up and you can manually add those.  It is usually less than 1% that need manual entry.

Thanks for the suggestion.  We don't have a default by condition that user can change.  That is a good idea.

I'll wait to see how popular this is before implementing.  In the mean time, you can import games to your collection with CIB as the condition and it might save you some time.

You can do this already.  If you visit a console page like N64

You will see a blue "+collection" link on the side of each item.  If you have added it, that button changes to orange color.  You can quickly look down the list and see all that are blue and are missing vs orange that are already in your collection.

Same thing works with search results too.

I hope that makes sense.

Thanks for that feedback.  Excluding variants would be a toggle, so you can turn it back on if it was implemented and turn off if desired.  Some people have asked about removing variants in the past, but I'm not sure we can implement specific variants to be excluded.  For example someone who wants Greatest Hits removed or another wants Limited Editions removed.  

I'll see how popular this request is before deciding on implementation.  I'll think about it in the mean time for how best to implement it too.

We can implement something that excludes all variants, but I don't think we can easily remove just "not for resale".  

What do you think about that?

Awesome idea.  The implementation would be really tricky for sure, but I can see lots of value to it.  I'll think about it more.  I've played around with image recognition stuff before but it is pretty tricky when there are multiple things in the photo and the game names are in different fonts.
