The demographics of video games have altered throughout the history of the medium. Initially it was widely considered that video games are primarily for males of a younger age, though this assumption has been changed as the industry marches forward. As of now, males ages 25-40 are the main demographic, contradicting the stereotype that only the younger generation, or a majority of them, plays the titles. The next step that developers had to take was attracting to females, which has gone significantly well, with the ESRB reporting that about %40 of PC gamers are in fact woman. Currently many games are targeting exclusively to woman. Disappointingly most of these titles are not critically acclaimed, though this is considered just the first step. At the same time Nintendo aims to deliver their titles to a wide variety of older people and younger people with a tactic known as the Touch Generation - making games for people who never even dreamed of picking up a controller. Titles like Brain Age: Train Your Brain in Minutes a Day! and Nintendogs show how successful this has been.
Males are still the primary demographics. Most video games are targeted towards males in their thirties, mainly shooters. The country in which the gamer lives also determines the main demographic - whereas shooters sell very well in America, the same cannot be said in Japan, where RPG's such as Final Fantasy and Dragon Quest remain top sellers.
