Guild Wars 2, The Witcher 2, Continent of the Ninth (C9)... and a vaste list of high quality and well designed games are using the same path finding engine, Path Engine.  (SUN) Soul of the Ultimate Nation  is one of the list.

Edit: The Game Engine is not all in a good game, you will need good concept artists, 3D artists... So SUN, is in the right way.
