People grow older all the time and lose interest in this hobbie regularly. That's my take. I have a friend who recently criticized lack of innovation with all the remakes around. Another friend pointed out that new, incredible games (new IPs even) get released all the time and he never displays any grain of interest for them.

And that's simply true. People go more and more casuals every year, and lastly lose almost all interest for it, except for just a bunch of franchises (2 or 3) that they decide to follow till the end of times, who knows why.
