NGL, I've spent more hours clicking REROLL in BG/BG2 than I have playing BG3, and that might not change even after I've played through the new one.
The old BG character creation process is so satisfying - the only functionality it lacked was the ability to jump back and forth between creation tabs.
Hey, if some shallow rolling interaction is all it takes to part people from their money I say toss it in there for single player! There is a whole generation of los..I mean 'customers' that will sit there roiling ability scores and pay Larian $60 to do it. Then 20 years later they will talk about how BG3 let them roll ability scores into the wee hours and it was the best part of the game and how they are nostalgic for that sweet simple time before they had an AI that played games for them.
