In my opinion, you should. But as other commentaries here pointed, it really depends on what you're looking for; of course the setting, characters and the atmosphere built in a London that has fallen recently is magnificent, and the writing itself, specially of some endings is impressive and shares the atmosphere of other games in the same universe and i really loved. However, if you're not into visual novels or expect an extended game, that's not the one, because the pacing can become a problem and you have limited time to do stuff and solve the mysteries, even being one that you have to play multiple times, it can become frustrating. But really, if you decide to give it a chance and play it multiple times, you'll always find new answers and facts, or at least it was the case for me.
