This game is an easy 4 star game and the reviews giving it 1 or 2 are just so wrong.
I'm well in to the game (about half way through) and I am hooked. The core gameplay of running around, driving, shooting are very similar to GTA or Red Dead however this is secondary to the core element which is pure detective work.
The story is engrossing and draws heavily on the film noire classics such as LA Confidential and Dial M for Murder etc.
You get given a case, you investigate and search for clues and question people and then this generally leads to a chase and a gun fight to conclude each 1-2 hour case.
The clue hunting is interesting and the questioning is a well worked mechanic which uses the high standard of acting and superb facial mapping to great effect.
Again getting questions wrong doesn't mean restarting and you can play through each case again to get better ratings should you wish.
There is less to do outside of teh core story than in say GTA but this keeps the story flowing and results in a more focussed game.
It is slow paced and if you are a COD Junkie I'd recommend a rental first, but one thing is for sure - LA Noire will be regarded as a classic. It moves games into a serious more cinematic direction and yet remains gameplay driven.
Well done Team Bondi and Rockstar!!
