Video games are big business. Stereotypical young males aren't the only market--for example, it's not uncommon for commuters to spend their train ride home with a Nintendo 3DS or an iPad. At home, they might unwind with a few rounds of Call of Duty while sitting on the sofa. But if you are addicted to your 3DS or your Xbox 360, I have to admit that as a PC-game fan, I'm sorry to hear it. Console and handheld game systems haven't always been the most popular platforms. PC titles once ruled the gaming world.
