It is important that GUI design and game design go hand in hand. As you work on the various features that are going to go into your game, it''s key to work on HOW those features are used at the same time. The interface is just as important as the feature itself. A good feature can be completely ruined by a poor interface. A mediocre or common feature can really shine with a seamless and intuitive interface.

I have nothing to add to this topic, but, since we''re on the subject of interfaces, allow me to mention the title of a book. It''s called "The Humane Interface: New Directions for Designing Interactive Systems" by Jef Raskin. I have no personal experience with the book, but it has received some very good reviews.

I have so many books in my reading queue. I''m too damn lazy for my own good.
