Murdered: Soul Suspect

• It's very short. Take your time, look about for collectables and do the side stories as you encounter them. You can beat the game in 4 to 6 hours and get the platinum trophy in a couple more if you are so inclined.
• There are only a few enemy encounters in the game and no actual "combat," per say. Most of what you will be doing is exploration and story, with a bit of easy puzzle solving - bit like LA Noire investigations.
• There's a point of no return and I *think* it gives a prompt before entering. If you'd like to know, it's
  the second time you go to the History Museum.
