Dead Nation,
inFamous,
LittleBigPlanet,
Super Stardust HD
Wipeout HD + Fury.
Looks like the diehard Playstation fans are the ones getting the shaft with this selection, assuming those people probably own at least 3/4 of these games. Granted, Sony's probably more concerned with the less loyal fans jumping ship, and those people may not have gotten a chance to play these games. I think i'll be getting Wipeout HD & Super Stardust, given that I have inFamous, have already beaten LittleBigPlanet, and have no interest in Dead Nation.
Playstation+ benefits them more than us, as it will act as a free trial much like Netflix does, and if you decide it's worth the cost to join, then it's a net gain to them.
You would think Sony would use this as an opportunity to make amends to the 3rd party developers they scewed over by messing with their release window by offering credits or paying the developers to offer their upcoming PSN games as an option on this package.
