Not only will the Game of Thrones RPG include new characters (who might be included in the books), but the game will provide an in-depth look at the world of Westeros.
While the existence of a Game of Thrones RPG has been known for a while, details have been pretty scarce up until now. Cyanide Studio, which is working with publisher Atlus on the game, today released a trailer and a lot of information about the title. I'm not going to lie: The game look like it could very well make up for the disappointment that was Game of Thrones: Genesis.
The game will have you playing as Mors Westfold and Alester Sarwyck, two original characters who don't appear in the novels (though George R. R. Martin has said he might mention them and/or the game's storyline in his later books). Mors is a sworn brother in the Night's Watch, while Alester is a Red Priest. The two characters proceed along parallel stories that players will switch between, and it sounds like they'll play very differently from each other:
Mors is a skinchanger and can slip into his dog to find secret paths or to listen in on conversations, and he can even follow a character's tracks through scent. Alester is a red priest who can set fire on his sword using wildfire, he can look into the flames to find secrets, at higher levels, can use certain fire-based magic.
While Mors and Alester have set appearances (which, admittedly, look pretty good as rendered by the Unreal Engine), it's being reported that their abilities and fighting styles are extremely customizable. Finally, the game sounds like it's going to be pretty substantial, with a story that crosses much of Westeros including The Wal and King's Landing. Players will meet characters like Queen Cersei, Varys the Spider, and Jeor Mormont (Lord Commander of the Night's Watch).
You can visit the RPG's official site here. Exactly when game is set to launch hasn't been revealed yet, though "early 2012" seems to be the projected date; the RPG will be available for PC, PS3, and 360. The overall length is expected to be somewhere around 30 hours of gameplay, though it remains to be seen how much of this time will be spent slapping Joffrey Baratheon in the face.
