I'm with you on the hyperbole. BG3 has been a massive success, but it's not really innovative or unique. In fact it's terribly buggy and is missing several features the community has been begging for over years of early access. It suffers all of the same problems other RPGs suffer from.
It's overall very high quality (other than the bugs), it serves a niche that is perpetually starving for content, and it encourages enthusiastic fans to buy copies for their friends. It has the names of Baldur's Gate, DnD, and Faerun all going for it. It landed smoothly in between the release windows of FFXVI and Starfield so it has no major competition. That's why it's blown up the way it has.
It's really good, I'm very happy everyone's loving it, but it's just... a good game that released with providential circumstance. Why can't it just be that simple?
It reeks of immaturity in general, or maybe more cynically, the perception of a bunch of nerds that have never had a sex life. There are so few games that handle sexual and romantic relationships realistically, and now that we have one nobody knows what to make of it.
Some characters take things slow. Opening up gradually, sharing some wine, holding hands and enjoying a single kiss on a night alone together. Eventually this ramps up naturally.
Some characters on the other hand are like, "you ready to fuck? I'm ready. Love? Never heard of it."
Both of these are normal and it's cool to see both represented in the same world.
