Hello there!
Would just like to start off by saying that I understand the things I will list might not be as important to others and that people have other issues they would address but these are some of the things I would like to see changed / added.

Also, I did not go through all the threads so if anyone mentioned things I add here, did not want to spam the same issue again.
First off, I am a huge dwarf fan in games / books / DnD so this is my main issue with BG3. The male model is really badly made. The way they hold themselves and move is really weird and looks like they are half paralyzed and just doing their best to move around and try to stand up straight. Also the male face options are pretty bad but could make them work if there was a single good hair and beard option to pick from. Beards in general are really bad but especially lacking dwarven styled ones.
Other than dwarf, I believe I read that there will be more races like half-orc and dragonborn which is really great, but I would also like to see goblins as a PC race. I think that would open a lot of interesting conversation options, especially in the 1st part of the game and the choices we can make so far.
A few immersion items I would like to list.
- quivers would be a welcome addition when using ranged weapons
- the option to show/hide shields when you have one equipped
- if weapons (swords, daggers...) could have sheaths while not drawn
- to be able to pick your clothing colour on details like shirt under a leather vest or the dye of the padded armour etc.
Gameplay wise
- being able to choose who talks to an NPC, especially when the conversation is initiated without the players consent (after a battle and such occasions)
- if food could be sent to camp and then used from camp storage and sorted automatically for long rests
Pretty sure there are other things I wanted to say but it slipped my mind in the process.
Thanks for reading! o/
