At a slightly-less-elementary level: Monopoly. Lots of decisions, but a lot of them are kinda "fake" - very rarely do you want to decline to buy that property you just landed on. And the game is often effectively over even before any trading or such. The pattern is little more than "land on the right spots, don't land on the wrong spots have other people land on the wrong spots, win."

Games with fewer meaningful choices and less exploitable patterns tend to be games that game enthusiasts move away from pretty quickly.

But they stay interesting as casual diversions or ways to spend time with kids for people who are less-game-oriented.

So I think there's two types of ways games are fun, and the latter one is simply "something to do together with friends and family" where the game itself is a diversion, not the primary enjoyment source.
