From PC Gamer: “Most people scoff a bit when I tell them that one of my favourite things about Mass Effect 2 is scanning planets. I get itthe whole act of clicking on a planet, watching a transition screen, turning said planet around its axis for a while until youve found a mineral deposit and then listening to the same lines over and over again as your probe launches isnt exactly a rousing experience. It doesnt have to be.”
