Meh, I hear for the AC3 that you will be playing an ancestor named Horatio, who took assignments directly from General George Washington to assassinate high profile British targets. Benjamin Franklin makes gadgets for you, such as an experimental set of modular bifocal glasses that allow you to view the world through many different spectrums (a la Predator). Free Masons FTW!!! Now this may not make it into the final build, but I've seen leaked footage of a lightning gun that Franklin also makes for you...
Seriously, this series shits all over history... Aside from that, though, I'm sure the gameplay will be a blast!
