Thank you so much for this screenshot.  Glad the sports card issue is gone.  I'll look into fixing the dropdown list to only include consoles include in your collection already.  

We will reply to the suggestion when it is being worked on and/or finished.  This request doesn't have quite enough votes for us to make it a top priority but we did see the request and we will prioritize it along with all other user requests.

Can you give me a screenshot of where you are seeing this?  I'm trying to find a page with this and I can't see one that has this.  Sorry for the problem, I will fix ASAP.

We will wait to see how popular this category is with people adding games and visiting those pages before we add games to the list ourselves.

Thank you
