Yeah, I said before that I do not think they´re going to use the full rules of spellcasting in a videogame. I have to add that I do not think they´re going to force casters to pick components like fleece or feathers to be able to cast spells.
There are subclasses that do not have access to arcane/druidic focus like rangers, Eldrich knights or Arcane tricksters, etc. so in PNP will have to get components and to have access to your component pouch you need a free hand... Something I do not think we´re going to see in BG3.
