The current "Games with Gold" game is "A world of Kelfings". Some lame Xbox Live Arcade game with lousy ratings. A total value of $9.99.
The current free PS+ games are...
PS3: ipp and obb Shadow of the Colossus Bit.Trip Runner 2 Dragons Dogma: Dark Arisen Hotline Miami (also on PSVita) ICO Poker Night 2 Uncharted 3 Xcom: Enemy Unknown LittleBigPlanet Karting Galaga Legions: DX Zen Pinball 2 Jet Set Radio
PSVita: wipEout: 2048 Gravity Rush Uncharted: Golden Abyss Grand Theft Auto: Liberty City Stories Hotline Miami (also on PS3) Sine Mora
Total value: $400 if you count Hotline Miami twice. $390 if not. And those games change every month.
My opinion in this is that Xbox Live has better service, but PS3 is cheaper, however ps3s cost more. A lot of people have Xbox live, so if you want to play with them you need to pay about 50$ a year, less than a dollar a week. Xbox live cost money for a reason. I think I will be getting one in December, I will probably name myself: [G3] Razor, or something of that nature. I will be getting a COD game hopefully Ghosts or BO2. I will tell you if/when I get one.
Shoot for the moon, even if you miss you'll float in the stars......... where you will float into the dark abyss and the lack of water and oxygen kills you =)
