In the early 2000s, mobile games gained popularity in Japan's mobile phone culture, years before the United States or Europe. By 2003, a wide variety of mobile games were available on Japanese phones, ranging from puzzle games and virtual pet titles that utilized camera phone and fingerprint scanner technologies to 3D games with exceptionally high quality graphics. Older arcade-style games became particularly popular on mobile phones, which were an ideal platform for arcade-style games designed for shorter play sessions. Namco began to introduce mobile gaming culture to Europe in 2003.[7] In the present day, Japan is the world's largest market for mobile games.[8] The Japanese gaming market today is becoming increasingly dominated by mobile games, which generated $5.1 billion in 2013, more than traditional console games in the country.[9]
