The Wii U version will use the tablet controller as a map and as part of a special "Eagle Vision" camera system.
Red Dead Redemption played a huge inspiration for the exploration and hunting aspect of Assassin's Creed 3.
Ubisoft had planned for an Assassin's Creed game to have the lead character be female but decided against it for AC 3 due to the historic era of the game.
Editor's Note: Since this is the Assassin's Creed mega post dreams are made of I wanted to add one more bit of information. The PC version is coming, but won't be the WASD/Mouse experience users might long for. Instead it is being optimized for gamepad. Alex Hutchinson mentions "I don't see us investing hugely in a mouse and keyboard setup. I think if you want to play on PC and you want to play Assassin's Creed, you have a controller." This isn't exactly a new thing, but it still is disheartening.
In regards to the Wii U version, Nintendo Power reported the tablet will act as a map; hold all the database entries unlocked in the game, and act as a quick select system for weapons and fire/melee modes. Also revealed was an exclusive "Eagle Vision" which uses the accelerometer to control the camera although no other details were revealed regarding the mode.
Some of the inspiration for the wildlife and hunting aspects for Assassin's Creed III was due to Red Dead Redemption. The original plans for exploration and hunting was very similar to Red Dead Redemption but once RDR was released, Ubisoft decided to change their plans and tweak their system to be what they call an "improved Red Dead Redemption".
Ubisoft also considered having a female character be the lead character in Assassin's Creed 3 but decided against it once the decision was made to use the Revolutionary Era as the setting. The official reason was them considering the Revolutionary Era as only a "man's world".
Historically there were some important women involved in the Revolutionary War but none would have fit with how Ubisoft wanted to make the game. Hutchinson said that the idea of a female assassin was "always up in the air" and that "lots of people want it," but the time period makes it too difficult... "It felt like, if you had all these men in every scene and (a female assassin is) secretly, stealthily in crowds of dudes, it starts to feel kind of wrong. People would stop believing it,” he said.
