I used to read all the Ultima Underworld walkthroughs around, a long time before actually playing the game, not to help me through it, because when I did, I had probably forgotten them all, but just because the world there looked so choerent, a very good narrative world.
I was pointed to an article about the original UU just few days ago, and I was amazed about how much the things described there were stuff that you could actually see back in the day already was making this game different from the rest...

About Aeon, interface has more sense than it seems, later on; fullscreen automap is ingame already; small automap was important to Florian and I would not hav considered anything BUT real time combat
