Forum games would be listed under the sub-forum General. Posting in Forums Games would not raise your post count, as it could be spammy. And so, yeah. You just make games that others would play. Like for ex: "Is the person above you known in the community", where you would comment about the person above you who commented on the thread on whether or not he/she is known. Or "Count to 100 before a staff member posts in the thread", or a "post what your desktop looks like", and my personal favorite is "Ask (enter someone's username) anything!" Where we ask the OP questions that they answer.
just a thought btw.
