Well you can't. Uh, because, you can't that's why. Now, usually, games with pre-rendered backdrops look pretty smart. Even the most ardent Myst -hater had to admit that the graphics were pretty darn, uh, pretty. The colours look washy, the detail is far from spectacular, textures are bland and the lighting is abysmal.
Animation is also suitably poor.
The interface, while being simple, is awkward and simply doesn't work. Just walking into a room can often take a few crafty maneuvers and the camera angles don't help. Very often you can't see where you're going, who's there and what they're doing. If all this wasn't enough there are a thousand other little niggles and gripes which make Rome truly awful. Firstly time can pass in the strangest of ways.
