I too have read George R.R. Martins "A Song of Ice and Fire" and did enjoy it immensely until it never was finished and I believe it might never been finished unless Brandon Sanderson takes over.
I just wanted to give a headsup to a few other authors I think you should try and read it, if you like George's epic story telling.
My first and foremost favorite author would be Steven Erickson's "Malazan Book of the Fallen" series. By far the most epic piece of fiction I have ever read to date. Huge story line with massive amounts of characters, magic, races, gods, and plenty of twists and turns that never seems to let up but all have very important consequences. Great read and there are enough characters that you will love some, hate others, and some who will probably not even interest you all. (In one book part of the story is from the point of view of an ox but it is still important and hilarious) I forgot to mention he has created some of the most humorous characters I have ever read.
Ian Cameron Esslemont is also a co-creator of the world of Malazan and is writing his own novellas that occur in their world.
Stephen Hunt is also another epic storyteller who writes novels in his unique world of magic and victorian sciences. He has four books out now and they involve everything from super hero like people to "Steam Men" (a race of sentient,boiler coke driven, steam robots) and everyone in between. Read "The Court of Air" and you will be hooked with all his ideas which he bases of actual scientific ideas and dreams from 18th century London.
Those authors have done something different and it works very well and I have enjoyed them greatly. After the next few months and you have some free time give them a go.
If anyone else here has read any of their works let Brad know either for good or worse what you thought of it and why you would recommend it or not. I think it would be awesome to have a game similar to Stephen Hunts world or the "Malazan World".
