That's interesting. I hadn't thought to check out non-english work. I would suppose translations are freely available.

I'm not familiar with Silverberg or Pohl.

Any recommendations?

I get what you mean a bit about the constructed complex huge new worlds.

It's a bit much to handle sometimes. Like the whole xenobiology angle of the enders game series, toward the end of them -- when Ender is out traveling at light speed to new worlds, etc.

Took me a decent amount of time and multiple attempts to really feel the strength of that book.
