OK, I'm going to start by saying that this was my first visual novel game and as far as introductions go, this was a great one! I will say that there were some sotries that I enjoyed more- my personal favourites were Van Helsing and Saint Germain. However, the way that all the characters' stories contributed to the overall story, means that you have to play all the stories in order to really appreciate Code: Realize - Guardian of Rebirth.
Overall, I would recommend this game to anyone who wants to try a visual novel, especially if you love stories set in a steampunk world. I definitely will be trying out more visual novels, in the future, especially the other Code: Realize games.
