Wonderful game with lots of strategic walkthrough opportunities.
Random events have a great influence on the outcome, this makes game unpredictable and challenging. Regarding other mechanics, they are pretty diverse and allow player to have quite a fun exploring and making decisions on what's next to come. Progress reuqires strategic skills, battles require tactics.
It is only a pity that fighting zombies becomes quite a disbalansed part when playing on higher difficulty levels, especially at the beginning of game. Same goes to some random events which can ruine everything if occured in early game. Still, love the game! Especially SFX and music - like a mediation to me.
