I'd also like to point out that I have observed that Bg3 - in many ways - falls into the classic experience according to the criteria I outlined.
I present as evidence what I call "The Sad tale of Lenore, Cleric of Mystra" - I will mark as a spoiler as some may not have put this all together yet.
Lenore was a Cleric of Mystra who lived in the Arcane Tower in the Underdark. According to Blurg, the Hobgoblin with the Society of Brilliance Lenore "was a reclusive person who stayed in her tower and studied Underdark plants." Lenore wrote a lot, was a fan of poetry and plays, and corresponded with a few close friends. Lenore also owned a dog named Myrna who she adored and even set up a complicated magical feeding system that was keyed to Myrna's coller. (If a player wears the dog collar and pushes a button in the Arcane Tower they get a free steak, uncooked). Sadly Myrna died, and Lenore had her buried near where you can find Filo the crazy Drow mage and the Hook Horrors and where the Bullette spawns. She would regularly visit Myrna's grave to leave fresh flowers and on one such excursion she ran into the infamous Bullete - which Lenore decided to befriend. She must have been at least somewhat successful as it didn't kill her instantly. She wrote to her friend/lover Amarith about it who expressed concern that she felt Lenore was trying to treat the bullete as a pet which was very dangerous. Amarith's words ended up being prophetic as the Bullete attacked and ate Lenore and you can find her armor - The Slippery Chain Shirt - in its belly.
So ends the Sad Tale of Lenore. Which you only find out if you read all her letters, visit the dogs grave, kill the bullete and put a few things together. I LOVE this sort of writing.
