With this criteria, the Dresden series is hands down the best option by and far. Game of thrones is the best fantasy series out there IMO, but it is fairly complex, especially at the beginning.
Dresden, on the other hand, is awesome. It is fairly easy to grasp, and it is probably the most thoroughly entertaining series I've ever read. On the whole, I put Dresden right below the Game of thrones simply because it is so completely exciting and entertaining.
BTW, the Coldfire series is very fantastic as well, with some philosophical elements in it as well.
I'm slightly jealous of you. I wish I could go back and read all these great series for the first time again
Also, I have these books on ebook on my computer. PM me if you want to know where to get them.
I'm currently reading The First Law Series, by Abercrombie. It is pretty damn good I must say. I've been plowing through the books because the fights scenes are incredibly descriptive and entertaining.
