If you have a PS3 then there is no reason to make this purchase. Why because PS+ has Vanquish for free right now and many other games. Plus, you can buy Tomb Raider on the PSN. You just spend 110, got the two games you wanted and tons more free games with PS+. Also because you spent over a $100 PSN will give you $20 in credit.
So dozens of free games for the next 15 months including vanquish and tomb raider plus $20 in PSN credit and you save 70 dollars overall sounds like a smart decision to me.
