Game Threads and Critical Thinking are the opposite poles of the forums.

Critical Thinking is for people who put a lot of thought into their posts, which are often more than a paragraph long. Game Threads are for people who click Submit before their brains figure out what they just typed.

In addition, you'll note that none of the so-called "game" threads actually have structured rules, conditions for victory, a referee, and a winner (or winners.) TWG has all of these things, making it a legitimate and respectable game. Ironically, that means that the place it is least suitable is the so-called "forum game" forum.
