How about clicking on a game tile brings up more information about the game such as a short description, screenshots, and box art. I think that would be a great option to have.
Agree with this idea. Player can press enter on a game tile to show up the games detail page first, before pressing enter again to play the games (or Esc/Back to return to games list).
The new (HTML5) version of GameGO will have a lot more customization options, next to changing colors in the config.ini file you'd be able to edit the HTML/CSS files for really the ultimate customization you'd get.
