This is probably too elaborate when there's bugs to fix, but I have always wished it was possible for users to store a favorites list that others could view from their profile.
Maybe even a statistic on the storygame pages showing how many people have favorited them? Not a necessary thing but just a nice extra detail that authors might appreciate. Which led me to think that the number of people who are in the process of playing a game and interested enough to have created a save even if they hadn't rated it yet would also be an interesting stat to track.
And as a related thing....is there some reason game saves have to be accessed from a completely separate page and not from the game itself? We can't get a Load button somewhere, either on the display page or within the game itself?
