Here are the things I went over for the Gamepad in these videos:
-Touch Screen Upgrading
-Touch Screen Inventory management
-Touch Draw directions & messages on the map
-In-Game Photo Taking with Gamepad free-look camera and editing
-Check in-game emails, objectives & item information
What I did not fully show:
-Miiverse posting direct from the game & placing a recorded voice message with an in-game photo as a icon to walk over during gameplay for your friends to see during their own play through of the game.
The Gamepad integration in Deus Ex on the Wii U is bar none the best implantation I have seen yet for any Wii U game. It's amazing that this console seems to truly be a 180 degree turn from the Wii, since in all honesty the controller is better suited for the these type of deep implementations in core games than games for beginner players that never played a video game before, like in the case with the original Wii. It will be difficult for Nintendo due to the fact that the crowd the Gamepad is best suited for is not the same audience that bought the Wii.
Let's hope the system sales continue to improve and developers take notice of the huge potential this controller truly has and take advantage of it in more games for the Wii U like Deus Ex accomplishes in great style.
