This is a great first part of what should have been a series.
Culpa Innata is set in the near future in a society that most of us would find very alien. The main character is an officer given the task of investigating a murder which is an event so rare in this world that everyone doen't really know how to start.
The best thing about this game is the detail of the setting. 'The World Union' where the main character lives and works is a society different to any of our own. In the game you not only carry out your investigation but interact with friends and colleagues to get a proper feel of what being in such a society might be like. There's also a lot of reference to the countries not absorbed by this society and how things are different. The writers have done an excellent job of giving a richly detailed picture of this world.
The main negative point of this game is that it is part 1 of 2 but part 2 never got produced. The principal aim of the game (ie solve the murder) is resolved nicely but so many more interesting questions appear on the way but never get answered. Very frustrating.
Other important points:
Gameplay: The game is highly non-linear. There are day cycles and you can only fit a certain number of things into each day but other than that the choice is very free. This makes the game DIFFICULT, particularly if you can't find a trigger for an event.
Puzzles: A nice balance of dialogue/persuasion, logic puzzles and inventory use.
Visuals: The 3D environments are well rendered but nothing very special.
Voice Acting: Very good on the whole with a few terrible accents.
Music: A futuristic dystopian nightmare. I turned it down when I could.
