From Rock Paper Shotgun:

Larian also pulled out some staggering stats to boast about the sheer size of their RPG. Baldur’s Gate 3 apparently contains over two million words (outsizing all three volumes of The Lord Of The Rings) and over 170 hours of cinematics (double the length of HBO’s Game Of Thrones show). Something tells me that we’ll need more than a mere month to get through this.

On top of that, the game contains seven playable protagonists with their own storylines and objectives, alongside 11 races and 31 subraces. The numbers don’t end there though: 21 classes, 46 subclasses, and over 600 spells let you mod playstyles to an almost extreme degree. Unsurprisingly, the team estimates that BG3 is roughly four times bigger than their last chunky gem, Divinity: Original Sin II.
