Games are also being designed with an older audience in mind, too. As technology has progressed, games have become more immersive and realistic.

This is very true. There's a lot more to choose from.

Another thing to consider, is the people who were young in the 80s and 90s when games consoles and a lot of the PC tech was making leaps and bounds, are now older. Perhaps timing with the gaming industry development, in relation to the age/decade the gamers started plays a part.
