Are there any very good games like Baldur's Gate 2?

My semester ended a few days ago, and I binge played Baldur's Gate EE until yesterday to celebrate. I have about three weeks before my schedule becomes completely immersed in work and studying, and I am wondering if there is anything else on that game's level?

I started Baldur's Gate 2 EE right after finishing the first game, and it is amazing. I have heard of Pillars of Eternity, Dragon Age: Origins, and played KOTOR 2 to death when I was super little on my brother's modded XBOX.

Is there anything else of this caliber? I would try tabletop, but I hate humans in large doses.
I am looking for something with a great single player campaign, at least a tolerable battle system, story depth and side character interactions comparable to Baldur's Gate 2, and if possible, great lore and world building. I don't care about how old the game is and I'm fine with shooting games.

I looked into it, but the long list of RPG games is daunting, and the reviews were not helpful. Also, I don't want to watch a play through and have a game ruined for me. I tried watching a few youtube reviews, but they got too detailed and started ruining the games I was researching, so I stopped watching them.

Thanks in advance!

Thank you @ChrisMaster69, @Astarlessnightsky, and @NamerOfStars!
I made a list and bought most of the games you all mentioned on GOG or Steam.

I'm going to play the Divinity Original Sin series first, then the Shadowrun series. After that, probably Planescape, Torment: Tides of Numenera, then the Vampires Masquerade series.

I'm going to save KOTOR 1, Icewindale EE, and Troika's temple of elemental evil for another vacation.
