Judgment in a box. Was in tears laughing for about half an hour.
Your trainer whilst playing as a mage... another laughing fit.
Taking down the Ferelden Frostback (first dragon), only to have this victory enhanced by getting sh*tfaced with IB at the pub.
Meeting Sera for the first time, literally felt like one of those cheesy romantic "love at first sight" moments... also, laughing fit when she starts explaining to me what the Red Jennies are about.
Getting the official title of "Inquisitor" and thinking to myself, I am the law.
Marching on Adament fortress, not expecting to get sent into the fade, having Sera freak out then responding to the situation with that classic line, "Well... sh*t".
The beginning of the Mythal mission, for some reason had me nostalgic for ME. (I don't know why, must've been the music).
