When asked for his reasons for stepping down, Kim replied, "Well, the JoBro (ed: Jonas Brothers) are about to go on tour again, and, well, you know. You only live once, and that one life should be spent seeing as many JoBro (ed: Jonas Brothers) concerts as humanly possible."
Okay, he didn't really say that. However, a Microsoft representative reportedly told Gamasutra that Kim "expressed a desire to spend more time with family, so that's why he's making his retirement." More details about the two-decade Microsoft veteran's departure should be coming in a press release soon. We wish Mr. Kim the best of luck with his newly acquired free time.
