This series is really one of the games that moved me. I've just finished a binge play starting from Innocence and I must say that this sequel is a major leap in story-writing as well as the gameplay. There are more rats in this game compared to the first. But it comes second as the characters are well-developed. You can see the evolution of how the game developers (Asobo Studios) imagined Amicia, Hugo, and the cruel world around them. The emotion that the game delivers is on another level. From the script to the scenery, it all adds up. Definitely worth playing!
P.S. Don't mind the performance issues, Requiem compensates it with the story, graphics, and the gameplay. Still hopeful, it gets patched to attract more players!
