After BG3 I will wait and see, both because of the release quality and to see if its a deep game or just a shallow romfantasy waifu game like BG3.
Seemingly you haven't played any waifu games to honestly make that comment, think do I. However, there will always be someone unhappy with what they produce.
Actually, their comment comes from a long held opinion of theirs in regards to BG3's overall weak writing and many plotholes, combined with updates heavy focus on adding romance features (To say nothing about the major marketing point of "Look, bear sex!" to which this trailer featuring a woman having sex with a lizard man is probably not inspiring confidence in them)
So while BG3 is a far cry from your average waifu gacha game... It has had considerable focus put on the romance aspect of the game.
That said, the Divinity titles weren't so into the romance aspect so if they continue making this game like they did Divinity games pre-BG3 it shouldn't be an issue. The crux is whether this is the case, or if they'll continue a BG3 style focus on romance given its massive popularity (Not only the game being popular but romances, especially Shadowheart and Astarion, being
the biggest discussion point)
