As you know already: On the front page and when you browse the GoG catalogue you see smaller windows with various games that GoG has to offer: Outcast, Gabriel Knight, Battle Isle and so on

What I have noticed is that I see these windows for games that I already own

Now my question to you is: Why would I want to see the webiste game suggestions for games that I already own? I think it would be a good Idea if you were shown games that you do not own. I'm sure many members on GoG (like myself) Own many, many games so they see this often

what do you think?

I think that might not be a good idea.
That would cause more complex and more time consuming SQL queries.
Right now the front page probably exists of a couple of cached pages which makes for a very light serverload.
Just my thoughts of course, I don't know how they've coded everything.

I rarely go to the front page, takes too long to load. Sometimes just to see if it's changed but . . . the front page is generally useless to me.
