I'm from eastern Europe and those green spaces are usually not very well managed. And they also end up looking kinda sad when you live there.

Rusty playgrounds, plants not managed and growing all over the place in a not very aesthetically pleasing way, completely destroyed or very quickly patched up walkways.

I do think it's still better than the American suburbs, but it could be so so much better if cities invested more into making these areas enjoyable to be in.
