Great historical atmosphere with issues of the time (bootlegging, racism, movies and apparently murders) in a great big city called Los Angeles. Its on open world game when it really did not have to be. All focus is on evidence collection and suspect interrogation, and with the fantastic facial animation its your job to separate the lies from the truth.
Definitely worth at the very least a rental, but I think this will turn out to be one of the Game of the Year contenders so why not buy it before the trophies are awarded and claim you knew it all along?
