I really enjoyed The Hyperion Cantos, and the first few Dune books I read a long time ago (may reread these now). Can anyone recommend some other books (or series) along these lines? Huge stories on an epic scale, space battles, cool future tech, etc.
The Honor Harrington series is great for epic space opera.
The Bobiverse is really good too, though less… grandiose? It felt more personal to me.
The Well of Souls serie(s) are great.
For less opera and more funny the Phule books by Robert Aspirin are good.
