Survival in a world with much larger, faster carnivores should be hard.
Staying sane in world with infinite lives, where you die to anything smaller than you because they are impossible to aim at, is harder but other games do the "die, rinse and repeat" model justice.
Resource gathering in a world whose physics actively aids the environment is ARK: Survival Evolved.

Physics should be a given, it should be the dinosaurs' behavior, the taming, the crafting that you have to figure out.
Finding a safe place to sleep (aka log out) should be the hard part, not standing in the exact correct place on the solid-looking floor to avoid falling through it when you log back in. And logging back in to find yourself embedded in a wall.

The AI can always path to you if its aggro, your loyal ones won't be able to return to you 45% of the time, even in line-of-sight.

You can build fantastic structures:
- tree houses to sleep in, then log in, fall to your death,
- houses on the backs of giant herbavores to sleep in, then log in, fall to your death
- boats to sleep in, safe from nearly anything except... logging in, where you find yourself in the water, pulled apart by sharks.... having fallen through 2-3 solid floors to your death

The same game premise, controls, taming method, combat, art, but on a real, robust physics engine - would be bigger than Minecraft, which pales compared to this. But I always know why I've died in Minecraft.
Several years of public beta, paid expansions, new features, still no solid floors.
