This depends largely on your expectation for what a 'game' should be.

Puzzle boxes, for example, have zero on ramp, and yet many many people enjoy them, enjoy the struggle of discovery.

Arguably the edges of mathematics and science are inhabited by similar people, living where the rules are ill defined, where there is much to be discovered rather than pre-digested and spoon fed.

I have little patience for games that don't spoon feed, so I get where you're coming from. I watched my brother play DF and decided I didn't want to spend my time like that, trying to parse ascii, trying to figure out how all the things interacted.

I also don't like puzzle boxes that much.

To each their own.
