I'm afraid I don't know what Hot Deals format is, and I thought about the pc gaming page but figured is more of a general discussion thread.
There are guidelines. So this could be Hot Deal topic. With couple of small modifications. Like having "Steam Fall Sale" in title (since thats what its about), then listing some of your picks and their deals. And to last your could talk about your own thoughts about it. The main point being sharing the deal, not discussion about what you bought.
Whereas PC Gaming topic is all about sharing what games and why you picked from sale.
