While Games With Gold is good if you already pay for Gold, it doesn't make me interested in picking up another Xbox 360. Halo 3 can be purchased for $4 and Dead Rising can be purchased for $3 as used titles at Gamestop. Wait for a buy two get one free sale and you get those and another for the cost of $7. .
It's no surprise that I'm disappointed with the US PS+, I complain about it every new thread that comes up about it, but it's far better than what Games With Gold offers each month.
