I probably qualify as a "new Oblivion player" as I indeed started Oblivion after Skyrim, but my first TES game was Morrowind, and that is why I couldn't bring myself to play much past Imperial Prison back when Oblivion was new - the setting of Oblivion just seemed way too traumatizing to bear back then
Years passed, Skyrim came out, I played it, I liked it, and I decided to try Oblivion again so that I can be able to get all the easter eggs and references to Oblivion in Skyrim. So I prepared myself for what I thought would be a chore. Once out of prison, I bumped into Aleswell, and that's when I realized that I'm gonna love Oblivion. It's been months now, and I don't see myself moving back to either Skyrim or Morrowind anytime soon.
Oblivion is fantastic once you let go expectancies of TESy atmosphere. When I play Oblivion, I don't play an Elder Scrolls game - I watch and participate in a Brittish comedy, and no other game has made me laugh so much. The humour is great and has my favourite flavour, and in light with this, Oblivion's setting - the Shrek's wify Orcish ladies dressed in embroidered velvet suddenly makes sense.
Not only Oblivion has a great humour, quest lines are also great, Thieves Guild missions thrilling, lots of unique quests with unexpected twists. Also, during my first playthrough I had to take notes to keep track on character developement - just like in good old times - a game that makes you think
In conclusion, I played Oblivion after Skyrim, and I rate Oblivion higher than Skyrim. Skyrim has what Oblivion doesn't have - TES atmosphere, strong presence and feel of Tamrielic lore, but in many aspects Oblivion for me is better. Also, the direction Skyrim/TES series is heading looks a bit scary - just look at all the Vampires and Werevolves threads in Skyrim forum section, or is it Twilight forum, with loads of Team
