My son is 15 months old now. I realize that the only games I want to play must be on a mobile/portable device (iPhone, VITA, 3DS, etc.) and I should be able to beat it and enjoy the story within 5-6 hours. That would be worth every penny, even at the standard $60 price point.
Maybe I should start a game company where we primarily focus on making games that are short and fulfilling to cater toward new gamer parents.
