Yes, that's possible. I don't think the evidence supports it, though. I agree that likely on average, as people get older, they have less time per week to devot

Yes, that's possible. I don't think the evidence supports it, though. I agree that likely on average, as people get older, they have less time per week to devote to gaming. Although it will be interesting to see how the first generation of gamers who retire (if they're able to...) will behave. But the question of their tastes is separate. It is not necessarily true that less time available => preference for simpler games. You can, after all, just play a complex game over a longer time period if you have less time available. One could get a rough idea about which hypothesis is true by making a sort of plot of game complexity vs average player age for each game. My impression is that the slope would be positive: complex games like EVE, X-series, DF, etc, do I think have very high average player ages. Another data point is that if you look at the competitive types of games favored by people in their teens & early 20s, they are FPS games, whereas MOBAs are more popular w/ mid-late 20s people, and I think we can say MOBAs are more complex (not necessarily saying they require more or less skill, though). I think if the data were examined it would support my thesis, but it is an open question and I was being a little hyperbolic with "I cannot imagine what mechanism..."
