Great to know.  Thank you.  I'm in the middle of adding Xbox and Xbox 360 PAL support.  I'll work on Saturn and Dreamcast support after those.

We won't add  that value to the value of each game because those items are not unique to each game.  We keep track of the value of each box, and manual, and cartridge/disc because those are unique to the games but those sleeves are the same for every game you add them too.  Same with protective plastic covers for boxed games.

Yes, there is some value to them but it isn't something we will add to the value of each game.

Can you give me the links to the items you found with the wrong prices on them?  I'll look them up.

Neither Silent Hill or Final Fantasy 9 came out for PS2.  They are PS1 games.

You can do this now.  Click the orange "in collection" or "in" button on any game page or search result page.  Then click 'add another" button.  You can add as many as you want to your collection.

Thank you

Most of our website users are on mobile phones now.

We haven't added PAL support for 360 yet, but we plan to add it later this month.  It will be added with those when 360 is live on the site.

You can download sales volume data now in the price guide download files.  And access it via API too.

We have a description section for each game, but we haven't filled it out for most games.  It is a field that we let users edit on their own.

If you view the "item details" section you will see a description field at the very bottom.

You can see an example here:

I'll leave this issue open though so we know how popular the descriptions are and if that field is one we should make more effort to fill in.
