Microsoft's Xbox 360 monthly free game promo, "Games with Gold," is being extended indefinitely. The program is essentially Microsoft's response on Xbox 360 to Sony's PlayStation Plus initiative on PlayStation 3 and Vita: members who pay the monthly or annual fee to the programs receive a variety of free games each month. Sony announced an extension of its program to its next game console, the PlayStation 4, back at E3 2013 -- anyone who already pays for PS Plus on PS3 or Vita is automatically a member on PS4.

Microsoft, however, won't say if "Games with Gold" will extend to its upcoming game console, the Xbox One."We're excited to announce we are extending Games with Gold for Xbox 360. We will share more details on the program soon. Stay tuned for our plans on Xbox One," a Microsoft spokesperson told Engadget. There are, of course, many other benefits to paying for an Xbox Live Gold account on the Xbox One, the least of which is the ability to play online multiplayer games.

Games with Gold kicked off in July 2013 with the aged Xbox Live Arcade title Defense Grid, and has since offered a smattering of other titles, from Crackdown to Dead Rising 2. This month's free games are Might & Magic: Clash of Heroes and Halo 3.
