Now i start a new character(my 7th-8th? i dont know) and surprisingly i find it like i play Skyrim for first time. There are two reasons for this. First radiant quests and second exploring. Despite the fact that i've spent many many hours in that game i still find it fascinating to explore skyrim since there are many interesting unmarked places(Isolated ruins, troll hideouts etc). If i add to this the fact that every time my character is developed slightly differently it feels like i will never get bored creating new characters lol
In Oblivion exploration was pointless and you had only your standard quests.This meant you would stop feel charmed by the game after a couple of characters
