According to ESRB, this game contains: Blood and Gore, Language, Violence
Parents, this one is a no-brainer. Liberty City Stories is packed with graphic violence, profanity, murder, violence against police officers and suggestions of sex. Some blatantly homophobic overtones are also included. It's not a game for children of any sort; this is the title that practically screams "For Mature Gamers."
Fans of the GTA series will most likely enjoy a presentation that's very similar to the console titles, but may be frustrated with how poorly the game translates to the PSP.
Deaf and Hard of Hearing gamers will be able to follow along for the most part, but the game's subtitles give no hints as to which character is speaking, which could be confusing in some instances. Also, incidental speech during gameplay has no sub-titles, although no major plot points are conveyed in this way. The only significant audio cues are the sirens of police cars when being chased, although this is somewhat alleviated by the presence of stars at the top of the screen that indicate when the main character is being pursued.
