So, it is it, full release on Sep -1. But there are still many mechanics in the Act 1 show case that aren't polished.
1. Exp gain:
the exp gaining pace is way too fast. For higher difficulty options, I hope it's about exp gain reduction instead of making enemy hit harder and harder to kill. For example, remove the exp gain from killing enemies. or making exp gain from killing irrelevant to whole party. Otherwise why would I want to use worm power to command the gnoll queen? I can simply kill them all because my party is so strong.
2. Quest Reward:
I hate the MMORPG style of quest reward selection in this game. It's killing BG3. For instance, there is a NPC before meeting Nere, if you give her back her boots, she will offer you a quest reward, but you get none of those reward if you simply kill her.
3. Vendor:
vendors got tons of gold and buying everything. Also the economy is broken, and none of them's inventory actually tells story that match the background. They are just so isolated from BG3. Lame.
