Cult Horror classic Alone In The Dark: The New Nightmare has been rated by the ESRB, as M for Mature, and listed for a PS3 release. The game is presumably coming out on the PSN’s PSone classic range, however the title was not listed for the PSP by the ESRB, which is a tad curious. The game was originally released on PSone, PS2, PC and Dreamcast back in 2001.
Thanks to Siliconera for the info.
