for me , i see the world building a stage in my way of writing a good novel, epic , whatever , in this way each stage has its important role , i can't see the point in comparing between one and another to determine who is the best of both , this is for no one sake at all . it's like i make you to choose between sun and moon , both are important to me and to everybody , by different degrees from one to another , so why putting ourselves in such bad situation ?

Very well put. I agree completely.

so , i have one comment on your words here , about making 1000 countries and so on .. for me i'm doing this right now , it may sound crazy , but i'm doing extensive worldbuilding process now , you may see me making huge mistake , but let me share you something..
as long as i make my huge process away from my main storyline and make them both away from my mind , i'm successful. my mind here is like the traffic officer , who says who passes and in which direction to go , here is the same.
what is the harm i get from planning these huge lines for my story and future epics and only tinny info mentioned at it ? you know i'm like building my own world history , it's awesome , and also crazy , but that's what i feel towards my epic , and so i did and still doing..
what i want to say here , is regardless what huge or tinny planning anyone does , the story still the main challenge here ..

Again, a very good take on the process. I agree 100%! So long as you don't bog down your readers with the nuts-and-bolts of your worldbuilding, I think creating a huge universe for your story can ensure consistency within your story, and give the reader a rich, full environment. I don't think it's necessary to a great story, even in the sci-fi or fantasy genres, but if you want to write an epic story, you obviously have to have some plan, and you have to give the reader a lot of information. You just have to be careful in how that information is relayed to the reader.
