Does this interface tell me what I need to know right now?
Is it easy to find the information I'm looking for, or do I have to look around for it? (Are the menus nested so deep that they hide information from the player?)
Can I use this interface without having to read instructions elsewhere?
Are the things I can do on this screen obvious?
Do I ever need to wait for the interface to load or play an animation?
Are there any tedious or repetitive tasks that I can shorten (with a shortcut key, for example) or remove entirely?
