The Journey Down: Chapter 1
Participating has no requirements. A simple "I'm in" will suffice. :) I'll pick the winners in three days, on Monday the 25th of March once I'm home from work, at no exact time. (Which will make it the early morning in the US by then, most likely.)
EDIT: Also say for which game you are in. If you do not mention which one, I'll assume you're in for both.
