Earlier this week, Sony Computer Entertainment Europe stepped up its PSP Go promotional activities with the announcement that it would be giving away 10 free games to new purchasers of the system in Europe or the Middle East. Shortly after that program was announced, Sony Computer Entertainment America stepped up its own PSP Go efforts, though not to the same degree.

　　Sackboy is thrilled to have his PSP price lowered to $20 or free. SCEA announced the PSP Go Digital Game Pack, a hardware bundle that includes the portable system and vouchers for three free downloadable games: Little Big Planet, Ratchet & Clank: Size Matters, and SOCOM: US Navy SEALs Fireteam Bravo 3. The Digital Game Pack is now available at major North American retailers and will be on sale until March 31, 2011.

　　Sony's promotional efforts won't end there. The company also unveiled its PSP Favorites line, a selection of games it will sell for $10. Already included in the list are Patapon 2, Loco Roco 2, Hot Shots Golf Open Tee, and Twisted Metal: Head On, among others. The publisher said the Favorites collection will be expanding in the future with third-party titles like Manhunt 2, Justice League Heroes, Silent Hill: Origins, Pinball Hall of Fame: The Williams Collection, and "many more."

　　As for the system's existing budget line, the Greatest Hits catalog, that's going to keep growing as well. Sony added four more titles to the PSP Greatest Hits selection, each of which now sports a $20 price tag: Gran Turismo PSP, Little Big Planet, Resistance: Retribution, and Secret Agent Clank.
