On the main page for the forums there is a "General Forums" listing. Under this listing it has a Newbie Central, General Off-Topic Chat, Hardware Software & Troubleshooting, and Art and Design, forum areas.
If you could find a specialized area like Newbie Central, Hardware Software & Troubleshooting, and an Art and Design listed there, you would also expect to find a General Gaming Area there, not in a sub-folder on the general off-topic chat. If anything PC games are more on-topic in relation to Half-Life 2 than a Newbie central.
This sub-folder thing is nice, but I think that a gaming forum should be on the main page not placed as a sub category. Many people already forget to talk about games in there anyway, they just use the general off-topic chat. I could see the Newbie Central placed in a sub-folder, or some of the other topics on the front page, but it seems to me like this general gaming subfolder was placed there simply to try out this new feature.
