I do find games with no rules tedious and not fun. The card game Fluxx, for example, I cannot stand.
I love the jankiness of these early ML games/stories/etc. and that's what you're missing.
I'd say a closer analogy would be Calvinball, where you just make it up as you go along.
Furthermore, I was dismayed when I learned (upon first time playing) that "It's easy to get started: there are no rules to read!" actually means "you spend the entire game reading rules!"
I acknowledge that this is not a very social (and somewhat rude) way to play this social game, which is why I typically politely decline to play it.
You can plan strategy. Whether it’s more or less likely to be thwarted I can’t really say. I try to be flexible with a few plans. The main difference is you are more likely to be accidentally thwarted than in other games.
Not to sound cruel, but, maybe you're missing the fun in imagination?
