This game grabs your hand and whispers "run". It is almost impossible to stop in the middle of a playthrough, and there is always that "just one more time" feeling when you end it.
It contains beuatiful, emotional stories, and stories of war and destruction. You an be a hero or a villain. You can make so many choices that change how the world will be when (if) you leave it.

This game is my most replayed game. a Playthrough takes some hours the first time, and a bit less after that, as some of the choice screens are resued - but with different outcomes.
It is a very fun game to simply play through and see what happens, but also to go about with a goal in mind - things don't always work out as you think they will, and some choices, while furthering your goal shortterm may harm you long term, and vice versa.
The game encourages deep thought and raises existential questions if you choose to play "as yourself", as well as if you choose to head for a goal.
You get to know the characters more and more on each successive playthrough - not all characters will be in every game, and some you may not meet at all.

All in all, very positive, very recommended.
