Imo kind of ridiculous to compare BG3 to Witcher 3, since Witcher 3 is better in every single regard except maybe companion stories.
Can it achieve the same level as Witcher 3? Yes, with a massive polish and overhaul for the definitive edition. Right now? Nowhere close, most of the stories don't feel memorable at all.
obviously, baldur's gate 3 isn't so bad.
even, i think that baldur's gate 3 deserve 90/100 when i finish act 2.
and, this means that i give a much high affim to baldur's gate 3.
whereas, when i finished the witcher 3 act 2 play, i only give the score 59/100.
due to the stupid castle crush and i have to say geralt is an unqualified assassin for assassinating King Radovid V.

i give the witcher 3 the score 75/100 final, because the final battle is good, but not a surprise, not beyond the view i can imiage.
go back to the topic baldur's gate 3 --
just, i am confused that why the screenwriter gives our players such a no fun tease -- an emperor who shields the main stroy.
and, everything is rushed in act 3 to force players to do the wrong decision in final.
i do irritate about this.
since the screenwriter somehow looses his/her emphasis.
the game emphasis is that a supreme existence who can order withers wants know "the value of mortals via tav's view".
in this light, the supereme existence aims via a proper chess game to know his desire and will give tav generous award.
however, i see the screenwriter how to set tav a trap and tease players.

note :
i think that we shouldn't think the story of baldur's gate is a trial to tav.
we should see tav is actual a chess player.
since i think tav was a dark urge 15 years ago who somehow resists all of his/her dark urge and pass the trial.
whereas, the dark urge didn't pass the trial and becomes one of the origin characters.
thus, tav is the supereme existence's chosen one.
