Again, it's like I have to keep saying it, but Skyrim takes itself seriously too. If you're looking for a serious RPG, there are TONS of them out there. Most of them have been named already. We don't always need more and more. Final Fantasy, Skyrim, Baldur's Gate, KotOR... There are so many out there that fit the serious archetype. Games like Divinity are rare, and I appreciate the light-hearted humour of the majority of it. No doubt someone will mod it to be more gritty and serious to take out the fun stuff, but personally, I love the fact it's more humourous.
