The horizontal menu bar at the top-right is now linking to sub-categories per game. This is only a temporary feature. Sub-sites will soon be implemented, giving each sub-site its own layout and separate left-menu blocks. This will reduce the visual clutter and keep things more organized. Once the subsites are live, the left menu will be removed. We will update you when subsites are implemented. In the mean time, you can use the menubar above.
NOTE: The Broodwar and Warcraft III: Reign of Chaos sections are empty. This is alright. I still need to add content to those.
