The only game on sale that interests me right now that I haven't already played is Hotline Miami and Antichamber, so today isn't a great day in terms of the games being on sale for me.
Everyone keep in mind that the daily deals (top of the steam sale) are when the games are the cheapest. You won't find them cheaper than when they are on the daily deal section of the sale, so pick it up if you see something on there you want.
