SEGA released HD remakes of two of its older titles today, a Sega Saturn classic, as well as a Dreamcast title featuring the Blue Blur himself. Both NiGHTS Into Dreams… and Sonic Adventure 2 are now available for purchase in HD from the Playstation Network.“Both of these titles represent something special in SEGA’s history, and that made them natural choices for the SEGA Heritage Collection” said Chris Olson, Vice President of Digital Business at SEGA Networks Co., Ltd. “NiGHTS offered 3D gameplay that had never been seen before on a home console, and Sonic Adventure 2 introduced rival character Shadow the Hedgehog to the Sonic the Hedgehog series. I hope players enjoy the opportunity to play these classic SEGA titles in their finest form to date.”Picking up SA 2 will give you the opportunity to purchase the additional “Battle” content released in the Gamecube version for $3.00, while grabbing NiGHTSwill give you free access to the NiGHTS Christmas levels originally only available through special bundles. Also, getting either game will net you a corresponding PSN theme.
