Here is my idea, when you are browsing games in the browse games function, when a game is in your collection or on your wish list, it says so just below the title in a smaller black font. Maybe keep the font size the same but change it to the color red so it stands out?
Because when I am browsing games for certain systems, looking to add games to my wish list. My eyes lock on title only and sometimes I miss the smaller black font below it because it doesn't really stand out.
Just an idea
