It is getting mixed reviews. One thing said no replayability, because the cases don't vary more do the results, and there is almost no way to die or lose. Still looks like my kind of game, though it said Heavy Rain was better.
I have died and "lost" a number of times in this game. There is no game where you can ultimately lose as you can replay from a checkpoint an infinite amount of times. This is no different. On side missions I have died on a number occasions. On main cases I have failed by being shot, failed my interrogation on multiple suspects at the police station, being made while trailing a suspect etc. I have also falsely accused suspects that are now on death row.
While no matter what do with your clues, the case will eventually end. However, what you do and how well you complete the case will ultimately determine whether you get 1, 2, 3, 4, 5 grade on your case. I have only received a 5 star rating on a small number of cases. The replayability for me will come in the form of trying to get 5 stars on each and every case after I get 100% completion.
I have hints turned off in the main menu and have never used "intuition points" while trying to find clues. Sometimes I have found all the clues, others I might be 2 or three clues off. I am usually not perfect on questioning witnesses either (truth, doubt, lie). This is where a lot of extra information might come from that I miss.
