It's no surprise to me that it's getting a lot more sales than they expected, and I'm glad to see devs get rewarded for making a quality product.
Yes, but naming the game "Baldur's Gate 3" instead of something like "Divinity: Dungeons & Dragons" is, unfortunately, a successful cash-grab. Which is to be expected considering that AFAIK _none_ of the original developers or writers worked on it.
