Finished it, it's good, it's not great. I won't bother going into a big list of positives and negatives, but I will say the complete lack of challenge really hurt the game for me, after homicide I really felt no pull to be a good detective, there's no win to the game at all for me, I don't feel any different five starring a case than I do two starring one. And the story wasn't particular good, which given it's prominence in the game is disappointing. I think after all this time, the amazing performance capture (which at times is just a distraction) and Rockstar taking it on as the publisher I was expecting something spectacular, and it's not.
With that however, I'm very excited to see what they do with the game going forward, the various DLC and potential sequel I'm excited about. I could see LAN2 being magnificent, it's a good first effort.
