You can make any game look good if you get the right angle and down sample enough. Unity looks great up close but the moment you get onto the roof tops and start being able to see buildings in the distance they become a muddy mess.
Right, which is why I and others have only been saying that it has its moments of visual splendour, not that it looks great literally all of the time. Every single open-world game ever made looks rough when draw distance becomes the primary concern, but few -- if any -- look as nice as Unity does when the engine can focus on rendering finer details.
