-As in Baldur's Gate 2, when we enter the city (assuming it's a true and active urban zone, hopefully), please give us a large tavern/inn with plenty of quest-givers, ambient chatter, dialogue, and events. Make it illegal to sleep in the city streets, and have guards approach us telling us off. If you are going to give us so much gold at the start (bit questionable), please make it expensive to enjoy the full extent of civilization, to reflect potential currency inflation. Either we need to get a room at an inn (of differing qualities, as in BG2), go to the sewers or some other hidden zone in the city, or head to the outskirts of the city to rest.
-More stuff outside of items and being shaken down to use our gold on please. Maybe investing in a structure that develops or a business venture. Maybe donating to a faction to help it develop, which could grant more quests.
-Don't want to knock the writing team too much, but the plot, characterization, and dialogue could be... deeper? More philosophical? Something that helps to express the worldviews of various characters, which would be a nice thing to integrate into party banter. Outside of shitting on the Moon Witch, can Shadowheart make a persuasive case for Shar and her corresponding worldview? Can Gale speak to whether or not pursuing forbidden knowledge/love is worth it if it destroys yourself and those around you? Can Astarion explain persuasively why someone who was tortured for a long period is not bound to care for others at all? Perhaps the intellectual and charismatic depth of our companions can be tied to their actual stats for Charisma, Intelligence, and Wisdom. While it was often a bit cheesy with some companions in BG2, they expressed their worldviews to each other and often challenged each other's ideas about the world, or concurred in a friendly manner. Do that, but better. I feel that many characters, party and NPC included, could express a bit more of their values and philosophies (where applicable, of course, and when relevant to narrative). Due to the tadpole being in the brain, I still feel that free will, autonomy, morality, and evolution are interesting themes to explore philosophically (if only through dialogue/chatter).
-In DA:O, interacting with the dog plays a cutscene of the dog and another companion. Can you do that with our companions, camp followers, or pets in camp at certain times (maybe only certain cinematics play after a specific decision or event)? It wouldn't have to be a lot of scenes, just a few sprinkled throughout the game. Maybe upon clicking the fire to rest, some camp members can chat around the fire.
-Are we too powerful too early? The DOS2 early game was more difficult and more restrictive than the BG3 early game. Is the difficulty too low? I thought level 1 characters were supposed to be weak. I'd like to keep all of our abilities, spells, and skills, but maybe have harder combat encounters.
