We can US, UK, Germany, France, and Australia for completed sales and then infer from the title what the item is and which console it is for.  We also look for completed listings by keywords in some of those countries as well.  eBay Japan doesn't really have much activity so we don't scan it.

We have that listed on the site here:

Are these amiibo figures or some other kind of figure?  If you link me to a photo or listing for what you are talking about I can look into it more.

Thank you.  I love closing "requests" like this one :)

I looked through a bunch of the sales records and quite a few aren't being added because the names are slightly different.  Shalom vs Sharom for example or Dragon Slayer II: Xanadu vs Xanadu.  

I did find a bug with one method we use to find these prices and I've fixed that now.  I've manually added some sales I found during my debugging.

We only allow one collection per account.  It would be considered your "video game collection" but you can then filter the entire collection to see your games by console.  We don't have a way to filter the collection by console brand though.

So I know more of the motivation behind this to see if there are other solutions, why did you want to create multiple collections?

I can take care of that for you.  Just confirming, you want me to delete your account?

I've added all of the chess games you mentioned as missing.  I've added one completed sale that I could find for King's Knight.

Please add any other missing games or consoles to the site as you find them.  I need to focus on some other development priorities right now so I can't add more of these in bulk until we see how popular this console category is with users.

I've added those games you listed as specifically missing.  They'll show up in search results within 24 hours or less.  

If there are other titles missing or variants, please use the add games tool on the site to add them.

I'm going to hold off on adding the more games in bulk at this time until we see how popular this console category is with collectors.  I need to focus on some other development priorities.

We have something similar for that already.  If you search for the series you can see all the results and sort them by price or popularity or alphabetical.  You can also filter out by region and variant.

Here is an example:

You can also see which of those items are in your collection or wishlist already and which are not.

Does something like this do what you are wanting?
