yes, older people as in up to the 40's. however, japan the majority is hitting 60s+, these are not gamers, not even in Japan.
According to the latest numbers, the average age of Japan is 45total: 45.4 years male: 44.1 years female: 46.9 years (2012 est.)
The average age in the US is 37 (just using the US for the sake of argument, there are obviously a ton of other places on this planet)total: 37.1 years male: 35.8 years female: 38.5 years (2012 est.)
So are those 8 years really making a huge difference in the gaming demographic? If anything, I would say that Japanese gamers are more the target audience for consoles, as they grew up their whole lives with them.
