It's a short list of deals as far as PlayStation tends to go, but I'm not about to complain when the alternative is usually hundreds of random filler games (and DLC) that aren't worth our attention.
If you're curious about PixelJunk Monsters 2, I'd advise a healthy dose of caution. It's an okay tower defense co-op game, don't get me wrong, but it doesn't come anywhere near the greatness of the original. I wouldn't tell anyone to outright avoid it, but you have to go in with subdued expectations.
Spot any hidden gems? Give us a shout. Outside of the flash sale, Dragon Quest XI is down to $30.
