I don't want to show off the user interface just yet — "God of War" isn't even out to the public yet — but personally, one of my favorite aspects of the game is what you see when you press Start.
The main menu, which you can access at any point in the game, has everything you need: It lays out your gear, weapons, and skills — which are all upgradeable in various ways — but it also contains much more than that, including detailed maps and a complete guide to the environments, creatures, allies, and enemies in the game.
There's a lot of complexity in "God of War," but none of it is hard to find, or to learn. Thankfully, a great deal of thought was put into making the menus both complex but approachable.
