Well, DF aims to be a fantasy world simulator.
In Fortress mode, you create your own fortress, and manage it from the ground up. You deal with the issues that arrise. Most of them are predictable but their extract details will very enough, where it causes you react.
It has emergent unexpected behavior, that keeps you coming back to it. These things keep popping up on their own.
Like, I was watching a kitty once, it followed its dorf to its bedroom, stayed in the room for a bit, and went away afterward.
Then there was a dog, whose owner died. The dog went to the spot, where the owner died, their room, and to his grave. And it just made me sad to see the doggy do that.
Then more recently, I had a cage of birds. They fly around the room they were in. That was unexpected but cool. Then I started to notice, that the number of birds of lowering. I couldnt figure out why. Little bit later, I notice a cat in the room. So I watched. A bird would fly out, the cat would hunt it. I just marveled at that behavior. It was awesome.
So on so on
The game allows for to have so much freedom, from its depth of continuing growing details. And even though you can predict, handle in large sweep what the game provides, its the details that you cant predict, that causes the fun.

But yea, I dont think you can do that in Minecraft at all. It lacks the capability for the complex reactions. It lacks the depth. It cant even handle water very well. It can barely do biomes.
