@Wilshire So, if I wanted a large scale big epic fantasy series, Lightbringer DOES the job? Is the world building actually creative, or is it First Law's #997463637 rip off, like most recent fantasy releases?
Not sure what you mean by First Law ripoff - I've not had that experience with recent stuff.
Hard to give a definitive answer on your question since I've only read 2 of the 5 books. Is it as big as Malazan or Wheel of Time? Absolutely not. The focus is mainly on two characters, the Prism (most power magic user in the world) and Kip (unimportant kid from a nameless village). There's several other characters that get POVs, but everyone's story exists to further the story of those two.
As is typical with fantasy, there's a big war going on. There's a bunch of politicking that goes on, but Brent Weeks tends to spend more time with action scenes than otherwise - kind of like Red Rising. From what I have read so far, Red Rising is a better comparison than say Bakker/Erikson/etc. Its smaller in scope, with lots of great magic, enjoyable characters with personality, marching/invading armies, and plenty of fight scenes.
The world building is good. The first book starts after "The False Prism War", which is some big thing that you learn about as the book progresses. So there's history, and its important, as well as varying degrees of racism from clashing cultures. There are a lot of different factions vying for power. Its a Hard Magic system, which plays heavily into the worldbuilding itself - magic is vastly important. It changes daily life, and while not everyone can use magic, lots of people can, to varying degrees. Everything from buildings to tools can be made of, or infused with, magic.
There appear to be gods (though exactly what they are and whether or not they are "real" remains unclear so far), fortune tellers, prophesies, special artifacts of significant magical power, etc.
btw, book 5 is supposed to be published in October this year.
Hope that helps answer your question.
