The Sims 4 Discover University - Gameplay trailer

It may seem odd to some how their marketing works, or their targeting, but its definitely working for them. Or else Sims 4 wouldn't still be around - with more years planned. Money-grabbing as the company is, they will obviously aim for the most profitable target, and right now, it's not the older players (since most of them are not sastified with the game). You may not see this audience around mainly because you're most likely to search for communities where you fit in.
I'm not a defender of Sims 4, on the contrary. But also I'm not delusional.
