I play D&D and RPG Games for almost 30 years now and I absolutely agree with the first post: a party size of 6 players is almost a must-have for BG3. And I would like to see it especially in the possibility to play a 6 person co-op game (and you can create 6 characters from scratch for your party).
Keep it up, we just tried BG3 in a 3player coop game this weekend, it's very very promising. Hoping to be able to invite our whole party when the game ships.
