The HD remakes of Sega’s Nights into Dreams and Sonic Adventure 2 have launched on PSN. The $9.99 downloads will be followed by the 360 versions on Live Arcade for 800 MS Points on October 5. In addition to featuring trophy and achievement support as well as graphical upgrades, Nights is bundled with the fantastic holiday-themed promo release Christmas Nights. PS3 gamers receive an extra bonus in the form of a free theme for either game with purchase.
Sonic Adventure 2 also has some accompanying DLC that adds Battle Mode. The $3.00/240 MS Point pack adds the extra content that was included with the later GameCube release.
