Game companies might have to adjust the way they treat their customers as the "gamer average age" keeps increasing. After all, many of those who grew up playing Mario are still playing. While there might be new blood lowering the average, there's probably a lot of "older" gamers than before. There's a reason you see many guilds like "The Old Gamer Guild" or "The Old Timer Guild" in most big MMO.
The part that annoys me the most is that, in order to appeal to a wider audience, most companies will try to lower the common denominator and claim something like "I, as a normal adult, don't understand this system. Make it more simple, after all, we have kids playing."
They don't seem to understand kids are actually extremely good at learning new or complicated things, and that it's adults who usually have a harder time keeping up.
I personally find that this struggle to make everything "simple" is killing the industry little by little. New players generally aren't dumb, they're simply new and might need some things explained, but I don't think they need their hands held for the entire length of the game.
On a tangent, I feel pretty young at 33 years old thanks to this thread.
