In the trailer for the Dr. in the game, you hear about all these different herbs/plants (drugs pretty much) that alter the game somehow. Maybe these "drugs" can be a means of explaining the protagonist's abilities.

Without giving away spoilers, I enjoyed the ending. It perfectly suited my direction of being a full-out paragon! Yes, many large elements of the story mean little in sight of the ending, but I still felt good about my decisions!

Definitely looking forward to investing in a Core processor. I used to be an AMD boy, now Intel's won me over ;)
