Sometimes it's just the logistics, planning, and structure that appeals to people. Other times it's maybe just the setting and environment having some kind of appeal.

And in some of these games there's sometimes a little bit of a creative design element to the gameplay, like when you try and design your own rollercoasters or other rides. Or building design in survival games like Minecraft.

There are a few games that are almost entirely centered on the conveyor belt gameplay though, which generally does not appeal to me at all. Satisfactory and Factorio are good examples of that.
