Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Panel From Hell 3 (LarPG) : summary of announced features

The changes they've made are not very minor tweaks, and you most likely have no idea how much programming, animation, acting and art resources went into these tweaks or how long they took, allowing for bugs etc. (Honestly neither do I, but wherever programming is concerned, there's always more work than meets the eye.)
Also, THEY ARE WORKING ON THE REST OF THE GAME AT THE SAME TIME. What we see in EA is a small portion. It's not like they're JUST working on refining Act 1 over and over again for us, they're also doing the rest of the game that we won't see until release.

Gods, so much negativity on these forums.
