Minecraft and things like it allow users to incrementally get deeper into it, with no cliffs.

Minecraft keeps on piling on new game mechanics, an infinite combinatorial mess of weirdness.

It has a whole panda genome dynamic.

But that complexity is hidden to you to start, you can slowly explore, from starting at "punching a tree".

When you design a lo-fi system, you can make it easy to tinker and experiment and get a fast feedback loop.
