In a situation with parallels in other categories, social and mobile games are not cannibalizing video game retail sales, Nintendo of America president Reggie Fils-Aime argued at a recent conference, according to Gamasutra.  Fils-Aime cited research that showed that the number of homes in which games were played went up from 67% to 72% in the last five months.  But that wasn’t just social gaming, as console ownership was increasing at the same time.  He argued that other forms of entertainment are being hurt, rather than traditional video game sales, and that social and mobile games may actually be helping other forms of games.
