During Nintendo's Investor Q&A, Nintendo President Satoru Iwata was asked by a worried parent what Nintendo's recommended console usage is. "Iwata's response started by focusing on a recent study Nintendo had completed, finding how socially acceptable gaming is as a form of entertainment. As per chart below, it appears to be lagging behind the likes of sports, music, movies and, most interestingly, television watching.
"Nintendo once seriously considered adopting a function which would force games to stop mandatorily, to prevent children from playing game, at the time that parents had previously decided. However [...] we finally determined to integrate a function to record playing time instead of making game shut down.
[...] in the case of Nintendo 3DS, we're contemplating incorporating some kind of system. Whether it'll be similar to one for Wii or we may add something more hasn't been decided [...] Nintendo is seriously considering such measures – probably most earnestly in this industry. Our arguments are so serious that people might be surprised if they were aware that a video game company like Nintendo is having such arguments internally," said Iwata.
