This game is by far one of the best if not THE BEST, interactive VN I have ever played. Since the very beggining of the first of the three games, you devolep an strong attachment to every single one of the main characters, and you see them growing up with every case and every day that passes.
For sure, there is no perfect game and some of the investigations or some particular case can make you easily bored if you want to explore every single dialog option (yes, I'm seeing you, Max case), but aside from those few moments, every character, every dialog option, every optional interaction, helps you to understand better all the motives and feelings of each of the characters in the game.
And then, you have the case 5 of the last game, the grand finale, the moment where every single character, every single choice from the past, and every interrogation left, all comes together in the perfect case and the best ending anyone could ask for. I really really loved this game, 10/10 experience.
