QUOTE : Games such as Mass Effect allow the gamer a freedom of decision that can be evilly enlivening or nobly self-congratulating, but these games become uniquely compelling when they force you to the edge of some drawn, real-life line of intellectual or moral obligation that, to your mild astonishment, you find you cannot step across even in what is, essentially, a digital dollhouse for adults. Other mediums may depict the necessary (or foolhardy) breaches of such lines, or their foolhardy (or necessary) protection, but only games actually push you to the line's edge and make you live with the fictional consequences of your choice.
