Semi-hijack but since Oblivion was mentioned...

Does anyone think a person who played Skyrim and Fallout 3 but skipped Oblivion would still enjoy Oblivion? Sometimes a step back in mechanics can lead to a less enjoyable experience overall which is why I'm asking.

Interested as well. I didn't play Oblivion, but played the crap out of Morrowind and Skyrim!
