Xbox's Games With Gold program will be offering three solid titles throughout the month of May, including CastleStorm, Mafia II and F1 2013.

The Xbox Wire has revealed three games that are going to be free-to-download throughout the month of May for those with an Xbox Live Gold membership. Xbox One users should know that last month's Pool Nation has had an extension, so you can download the billiards title again if you missed it last month. The tower-defense game, CastleStorm: Definitive Edition, is the new free title Xbox One users can download next month. Whether you're playing as a knight or viking, you're bound to enjoy CastleStorm's stronghold and siege-based warfare.

From May 1-15, Xbox 360 owners with an Xbox Live Gold subscription can download Mafia II. If you're a fan of The Godfather or Goodfellas, this game is for you. You'll play as mafioso Vito Scaletta in his crime-filled rise to being the criminal kingpin of a post-World War II America. For the rest of the month, you'll be able to download F1 2013, which features all kinds of drivers, cars and circuits from the 2013 Formula One World Championships. Is it seriously too much to ask for something else instead of F1 2013, or at least the 2014 version?

We have to admit, this lineup is a huge letdown compared to the excellent month Xbox's Games With Gold program just had. Child of LightTerraria, Gears of War: JudgmentArmy of Two: The Devil's Cartel and Assassin's Creed IV: Black Flag for April compared to CastleStorm, F1 2013 and Mafia II for May. We know not every month can be amazing, but still. Come on, Xbox; it looks like Sony won another one.
