@gregski, I don't think
@saoe is actually wrong, we do have such similar threads for music and movies/tv which are quite active and well running, and since we are all gamers here primarily the number of threads for a particular game will of course far exceed one of the other mediums (like a band or a show) so it makes sense having a sub-forum for having a thread specifically for each game. It's less cluttered that way. and more organized than messing up off topic, and that was the intention.
But suppose if I'm playing a game "X", it makes more sense for me to post in a "what you playing today" than posting in a thread just for it, leaving it dead if not many others are interested in it. And a person is more likely to view an-going discussion and look at what people are talking, and in that process discover something than viewing one specifically (or not, if it's lost being deeeead)
Like if I tell you in my personal experience, I remember watching Vikings because I saw people talking about it one, and there was never a thread specifically for it. And god I love that show, and I have people here to thank for. Now I probably wouldn't have come across if not for that collective thread wouldn't I?
So yeah, in short, it's not exactly a "wrong" idea.
