Return games by genre

I would like to return games by genre. I pull a list of the genres with http://www.giantbomb.com/api/genres/?api_key=[key]&format=json and would like to now return games pertaining to a specific genre. I have looked over the documentation and do not see a clear way of accomplishing this. The site clearly has access to this type of return for example http://www.giantbomb.com/games/?genre=1 provides all of the Action genre games.

I would like to do this too. I'm going to stack all my RPGs cartridges and discs, march them down to EB Games and demand a refund!!
