I spent over 50 hours with BG_III. And it was probably the worst 50 hours spent. I spent over 50 euros on it. And it was probably the worst 50 euros spent. After those damn 50 hours, I haven't managed to finish the game and I won't finish it anymore because I'm just fed up with it.
The advantages of the game include choosing the type of penis and the ability to go naked. And that's all concerning the game in terms of both advantages and originality.
I would describe the main (only) disadvantages as follows:

- The game's plot is complicated and confusing. At some point you don't know what's going on. Lack of coherence and consistency.

- The game is secondary to the creators' earlier titles - Original Sin I and II.

- Graphics are so-so for today's times.

- The turn-based combat system is hopeless - each battle drags on forever. I have no doubt that it was invented to artificially extend the playing time.

- The characters are weak and it is practically impossible to achieve a comfortable level of their combat capabilities compared to the opponents. Winning a more serious fight, even on an easy level, is almost impossible.

- And generally - if the game offers a graded level of difficulty, it should probably be easy on the easiest level! Meanwhile, the plot leads astray from which there is no way to get out. Apart from masochists who look for a challenge at every turn, there are also normal people in the world who would like to play a game for fun. BG_III (on the lowest difficulty level) is not for such people.

- To sum up - this game is a disaster. Calling it BG_III is an insult to BG_II (and BG_I too).
