Why does it not show games that are similar to what I'm already looking at or within the same genre/series?
I also see games that I have wishlisted or already have. Why would it advertise what I already have or want?
It also doesn't ever change. It is the same 4 games every single time no matter what I'm looking at.

It isn't the same every time, but I do see the note of it being practically useless with suggestions of titles already in the library.
