@ewalthour: It does stack. I don't know why he thinks otherwise.
Both of you sound like babies. I own only one of those games, but everything else interests me enough to warrant the download. I don't see how PS+ can be criticized with the volume and quality of IGC games, sales, and extras that are offered. At times there are sales that beat Steam, like that $2.99 Walking Dead Season One deal. Mortal Kombat and Rayman Origins were $5 in the summer. It's hard to argue PS+ isn't awesome unless you already own most of the games available. Even then, getting a year for $30 and taking advantage of some of the bigger sales and a few free games makes it worth the cost.
