Sounds a lot like me after I put hundreds of hours into the 360 version. Particularly the strangeness of the Dragonborn being largely irrelevant after finishing the main quest. In Oblivion the player was subjected to praise and an overuse of the voiced title "Hero of Tamriel!" but in retrospect I preferred acknowledgement of main quest completion.
Beware the PC version. With a good set of mods attuned to your preferences it nearly becomes a different game. For me the inclusion of a great deal more random encounters, similar to Daggerfall, breathed new life into it. Just haveta' wade through the "clean women" glut of mods that Gerstmann so perfectly summarizes.
