Looking at
movies page, there already is a system to sort movies into categories, so at least by the looks, it shouldn't be hard for someone familiar with the code to add a "Game: Super Metroid" category (say). But for all I know, I might grossly underestimate the actual work involved.
Don't get me wrong, "no one has time" is a good enough answer for me. I don't have time to do this either, even if I were given access to the site code. I know what it's like to run a hobby project. (I was more interested in whether there is a strong technical issue, or philosophical disagreement with allowing more publications for individual games.)
