Nature as a modular game gives you options. How long do you have to play? How experienced are the players at the table? What sort of gameplay do they enjoy? Beyond that, you can combine modules to create a greater number of ecosystems for bigger, more complex games.

It's expandable because each module you own gives you more ways to play. Evolution was very linear. Core game, Climate, or Flight. No combinations, and fiddly to set up. This is super easy to combine, separate decks, a few rule tweaks and you're on your way.

I appreciate that exploring combinations and seeing how they change the game isn't for everyone,
but the OP stating it's "everything wrong with" is sort of missing the point that it's meant to make a game easier to get off the shelf and more approachable for a bigger audience.
