I'm a little afraid of that link, but just off the top of my head:
Cyberpunk had a dong slider in '20. Battletech had the separate-gender-from-sex-and-pronouns thing in '17 Dragon Age Origins already had far more complex relationships in 2007, including gay ones. The amount of possible outcomes for the relationship with Alistair alone should convince one that BG3 isn't all that revolutionary in that regard.
