+1 i agree with op's post and i actually have also shared some similar thoughts other places on these forums regarding how the tag system that larian is implementing for bg3 really has the potential to create a dynamic story for each playthrough - ie each playthrough you could select on pc creation or earn throughout the story different tags that would have possible story hooks or gameplay mechanics that your pc could explore as part of their adventure (not dissimilar from the mechanic in ME where you would select parameters of your shep's background)

these tags could be grouped into several different categories, such as
-race,
-class,
-background/profession,
-alignment (im a fan of alignment [including being unaligned], but also agree with others that selecting a certain alignment shouldnt restrict a player in how they play or what choices they can roleplay),
-follower of x deity (which i think should be a staple of character creation in the FR setting - there are currently 20 deities in ea so far i believe, but the setting has a numbered variety more),
-and hometown/plane (ie. baldurian, yartarian - the city attachked by mflayers, waterdhavian - where gale is from, planar - already in game hidden for a gith tag and maybe for tiefling too?, candlekeep?),

but im sure others could also come up with other possible ideas to add to the tags above. i also dont think that there should be any hidden tags as there currently seems to be - i would want to know and be able to review what and why i have certain tags

- i think that adding several tag options to the custom made pc regarding what they were doing either in yartar/whatever city they got snatched up from (on the run from the law/hunting down an old rival/looking to collect the bounty on your first successful adventure) or possibly what your pc was doing during the whole descent into avernus adventure (i would be surprised if wotc was against an opportunity to plug a tabletop adventure) could also work to make your pc feel more unique/alive and could open up some plot avenues in the later acts, such as following up on your initial business in the city before the mindflayers grabbed you.

- i think it would also be neat to obtain tags as you play through bg3 that npcs/the world would react to in later acts as well, like whether you sided with the goblins or the grove during act 1 (tbh, now im having trouble thinking of decisions of that scale in act1 that could carry weight further on in the story - any other suggestions here would be helpful, but maybe that is also a function of what i think are a fairly limited number of significant binary choices in game, but just my current impression)

-related to another other comment above, i also think it would be a neat system to implement a party reputation dynamic in how the world of bg3 views the pc and the party's actions through the story (the og bg games did a sliding scale of basically good/evil reputation) that would be separate from any individual character alignment mechanic, but im not sure the best way this would be implemented (in the og bg games if your party reputation was too good then your evil party members would grumble and vice versa)

-lastly, i think a codex or encyclopedia would be really helpful for both new players and players new to bg/the forgotten realms for both 5e/bg3 rules references where players could review 5e rules as implemented by larian in bg3 and also to read up on pertinent forgotten realms related lore
