One of the elements that is a key to entertaining people is novelty or surprise. You need to be able to catch people off guard and pleasant ways and give them things they don't expect that connects with them. If they videogame industry then feels that it has to follow a normal pattern of other industries, where you see something that works and keep offering the same over and over, then it is going to bore customers. If you end up being like Midway, that late in the game felt they needed to come up with a WW2 based FPS title that no one was asking for, you end up like Midway, which is broke and sold off.
And, in the process of entertaining people, you need to find cost-effective ways of doing it. If you are going to drive production costs up to get it, you are asking to go broke. The cost of entertaining can't drive up through the roof.
Nintendo seems to get this, which is why they are successful this generation. I have to say so, as Kirby's Epic Yarn, with me, managed to surprise me, and really catch my interest. And 3D without glasses is another one. I get this buzz about Nintendo that they are cool, without trying to be "cool".
