They got 1200 Mass Effect fans into one room at PAX East this weekend. They—some folks from the game's development studio BioWare—asked people to raise their hands if their favorite game was the first Mass Effect. Some raised their hands.
Mass Effect 2? Most people raised their hands.
Mass Effect 3? Few hands went up.
And then they asked who favored FemShep, which I guess is another way to ask who plays as her. The very short video here shows the result.
