After Morrowid Oblivion IV stands out with deeper gameplay, sumptuous sets and greater fluidity of the characters. Quests are many and varied, and the story is compelling to the end (I'm in the second part). I have not yet played the two extesions. It is regrettable that some dialogues articulated characters remain silent ... or sometimes downright recommendations or directions in English! That aside, Oblivion IV remains an excellent game and very long.
