In the year 2049, the governments of the world switched to unmanned aircraft for combat in an attempt to save lives. By doing so, they decommissioned thousands of jets and their fighter pilots, ironically destroying the livelihood of those they were trying to save. Years later, these planes appeared on the black market and were sold to the highest bidders. It wasn't long before an underground emerged, featuring ex-fighter pilots, smugglers and wealthy hobbyists piloting the decommissioned aircraft. In a competition of fight and flight, these pilots heavily modify their jet fighters to outrace and outduel the competition to win fame, glory and fortune. Welcome to the world of M.A.C.H. Modified Air Combat Heroes rise through the ranks by defeating rivals and unlocking customized parts and planes -- 180 over-the-top configurations possible across 11 planes -- for enhanced speed and weaponry. Gamers will take to the skies for intense aerial racing action and deadly air-to-air combat throughout a variety of environments and can choose from multiple gameplay modes. Arcade mode is designed to throw gamers into the action as quickly as possible and, although only one plane will be available initially, progressing through the Career mode to unlock other planes will gradually give access to the full Arcade experience. Career mode consists of a collection of high-octane tournaments spread over various landscapes. As gamers progress through their career from a Rookie through Pro, Ace, Elite and finally to a combat Hero, they'll gradually win access to enemies' planes and earn cash, which will enable players to upgrade capabilities and keep up with the competition. Each Challenge tier consists of five challenges -- MACH Melée, MACH Dash, Time Check, MACH LAP and Dog Tag -- in different locations in the quest for ultimate glory. Multiplayer – Players race or dogfight against up to eight opponents over an Ad hoc wireless network or via Game Sharing with rival PSP system owners for the ultimate deathmatch experience! (Game sharing mode requires only one copy of M.A.C.H.) [Sierra]

Mixing miniature mayhem with maximum multiplayer racing, Micro Machines v4 features knockabout, breakneck racing in the fastest scale miniatures, complete with explosive weapon power-ups. Letting you loose with hundreds of vehicles, each with distinctive performance abilities, you'll be racing your inch-long miniature motors on the wildest tracks where everyday household objects appear immense in size and can become lethal hazards. Sport cars, street racers, stock cars, 4x4s, beach buggies, lowriders and muscle cars are just some of the Micro Machines models you'll be taking out on the improvised tracks around the Micro Machines house, garden and - for the first time - beyond. Spin out around the breakfast table littered with cereal spills, tear through the kitchen but avoid literally burning tyre rubber on the blazing hot cooker, turbo boost around the pool table (while avoiding the treacherous pockets), or hit the gas as you drive around the rim of the bath, carefully negotiating the ferocious waters pouring over the edge of the bath (because someone left the tap running).

[Downloadable Game] Developed by Polyphony Digital, this driving game features an all-new course for players to be the first to drive a Ferrari on a PS3, as well as have the option to select a car from nine other worldwide manufacturers that include Infiniti, Lotus, Mitsubishi, Nissan and Suzuki. Available only for a limited time, Gran Turismo HD Concept takes full advantage of the PS3 hardware performance by providing full HD 1080p resolution and next-generation car physics ushering in a new era of racing for the gaming industry. Upon downloading Gran Turismo HD Concept, PS3 users have access to the Eiger Nordwand course and can compete in Time Trial races to collect and unlock new cars. Upon unlocking the initial 10 cars, the player has access to 10 more "Tuned Cars," as well as access to a new driving mode called "Drift Trial." In the "Drift Trial" mode, the player can master the art of drifting and achieve ultimate control of their car. Furthermore, when connected to the Playstation Network, the player can upload their times and view the Top 10 rankings for each car and mode, as well as play and save replays online. In "Time Trial" mode, the player selects a car and must complete the Eiger Nordwand course within the target time indicated at the top of the screen. Each time the player beats the target time, a new car is unlocked and made available for selection. As stated, upon unlocking all of the cars, the player can access tuned cars, along with the option to race Eiger Nordwand in the opposite direction. In "Drift Trial" mode, the players drifting technique is tested, rather than their lap time. The player earns drift points based on their drift angles, racing lines, and speeds within evaluation zones located at various turns on the course. For each evaluation zone, the results are based on the number of flags and a numerical figure. The point total from all zones determines the players drift points for the lap and is counted toward the rankings. [SCEA]
