I thought we already did this discussion in another thread some time ago?
My views on this are quite well known, I think. I do need to add, though, that I haven't seen any evidence that the game was able to "bring in non-rpg gamers." That's a notion that's bandied about but I haven't seen any hard evidence to support such a claim. For me it is more that the rpg gamers group is in itself quite large. But it is an internally divided group, consisting of cRPG, ARPG, JRPG, MMORPG, and other such subgroups, who don't necessarily like games from their respective out-groups. But BG3 had appeal across all the subgroups within the RPG fans group.
Anyway, here's what I see as the things BG3 brought that made the game attractive to people outside of the hardcorre, old-school cRPG group:
SEX (specifically, interractive sex with lots of permutaions, variations, and options)
Some 170+ hours of cinematics
Full voice acting
Couch co-op
Story and characters that resonate with and appeal to today's young people (Gen Y and Gen Z) (I won't give my specifics on this because that will surely upset/anger some people; suffice it to say I have a lot of negatives toward the character, personality, and attitudes of today's younger generations, obviously with exceptions granted)
