Around the middle of 2012 Gamespot and GameFAQ's shared forums split apart.
Now there is single, cross-platform boards for individual games.
Under different circumstances there might be a genre board or a game series board that the game falls in to in the forum links on a game's page, but I don't think I've seen those in a little while.
You can see the GameFAQs boards, but only in a read-only view, by clicking the arrow beside the link to the game's forums (example in [url=http://image.com.com/gamespot/images/2012/82/gameboard_37752_screen.jpg]this picture[/url]!)
here's a [url=http://www.gamespot.com/news/gamespot-and-gamefaqs-break-up-6367594]community announcement[/url] about it from a while back!
