The same level of good? I consider Witcher 3 to be the best game I've played. Is BG3 on that level?
I played my version if Witcher 3 on the Switch when it was first released a few years ago, btw. Graphically not as good as the PlayStation, but still amazingly good.
Short answer:
Yes. It's equally as good...in its own way.
Longer answer:
TW3 and Cyberpunk are much more crafted and cinematic experiences with a grounded, gritty storyline that gets into mature narratives and nuanced dialogue. It feels more "real" in many places.
BG3 is a bit more "in your face". Perhaps more in common with cartoon dialogue, but it does NOT feel like a cartoon in practice. There are some nuanced moments, but there are more on-the-nose moments than in games like The Witcher, Dragon Age, or Mass Effect. Don't let that dissuade you, though! It does what it does very well -- it all seems to
fit. Constantly.
The gameplay is what sets BG3 apart from anything else. The choice/consequence thing is taken to an insane extreme. Everything -- literally everything you do -- can
drastically affect outcomes. Everything from the class or race you play, powers/spells/abilities you have available, to the dialogue options you choose, to quests that you either have or have not completed (sometimes in which order), to where you have been in the game world or what items you're presently carrying, to the composition of your party and the relationships they've developed can and will drastically alter the options you have at any given moment, the story you see, how other characters react to you, and where the story will wind up going from there.
While there are central "plot milestones" that will always play out in roughly the same order, the different ways of reaching each milestone and what you're trying to do when you get there will create completely different story lines and gameplay experiences. This is where it really shines: branching story. Suffice it to say that most games are a stick with a few twigs sticking out here and there. TW3 is a whole tree with branches everywhere. BG3 is small friggin' forest. It's like nothing that has ever existed before.
