"Is there anything else that's sorta like this?"
Thats why I'm curious about Rogue Trader, whether that will manage to pick up anyone from BG3's release, plus it's including co-op which might entice those types of players too.
For the current modern cRPGs, as far as Steam Charts go, none of them really saw a major uptick on players (hundred at most, and aside from DOS2, go figure). Also, oof Wasteland 2 with 11 people.
Owlcat really missed their chance for not making and marketing a Griffon romance option for Ulbrig
