I have decided to list links to genres on the homepage of Playpile. This way, people who come to the site can merely click on one of the links to pull up search results on that genre of games.
Fortunately, my design allowed me to easily add the links in a way that merely does a search based on genre. The preferences that the user might have set affect the genres listing just as it would a search. It all ties in very nicely.
Also, since I order listings by date added when the search results indicate they are equivalent in relevancy, all the games listed by genre are ordered by the date added. So, users always see the newest games listed first.
