It's a week long sale where a LOT of games are on sale. Every game on sale has one day during the week where they go "super sale" and are off for an even higher amount. After their respective days, they return to the normal sale.Jiffex said:OT: This will be my first Steam summer sale, is it a list of games that go on sale each day for one day or a list of games that are on sale for the whole summer?
Sometimes there are fancy fun competitions and sweepstakes and stuff.
