For me, DnD is a rule set, nothing more, nothing less.
BG3 will have some form of alignment because it is a DnD game.
Personally I do not like the alignment system.
You have to put every intelligent creature into one of 9 boxes, from lawful good to chaotic evil.
I think of fantasy stories as a mirror of the real world.
A fantasy story shows a conflict and the player (in case of a video game) can chose what this story means for the real world, or if it means anything at all.
In a fantasy story the conflict is often simplified or taken to the extreme in order to make a point.
Personally I do not like the Tolkien way.
Saying that orcs are evil and killing them is good makes as much sense as saying nazis are evil so its OK if I kill somebody just because he says something racist or he believes in a conspiracy theory that illuminati mind control us with chemtrails and they try to replace the population.
I am an individualist and consequentalist, so I believe it is only OK to punish a creature when this creature has caused harm to others. Killing others is only OK if you defend the life of yourself or others, else you are nothing but a murderer. Being evil is not a crime by itself.
As for DnD I like the games most that turn everything upside down.
PST is fantastic, you have nice demons, evil angels and chatty undead, all of this to discuss the question "What can change the nature of man?".
KotoR2 is fantastic. Kreia critizises you no matter what you do and she tells you not to believe her.
Thank you Chris Avellone.
Disco Elysium (not connected to DnD at all) is a great successor. Your main char is not a hero, but the ultimate catastrophy of a human (drunk, stoned, no memory, no money and a head full of insane ideas)
If I have to make a game the moral stuff would be similar to the witcher series.
There are tough choices and significant consequences, but the game does not put a label (good, evil, law, chaos) on them.
Radovid may be lawful evil by DnD standarts, but putting the lawful evil tag on him would not change anything.
In every DnD game the were options where I have asked myself why is this tagged good or evil and sometimes I disagreed with the tags of the game.
In the witcher series every result of my actions made sense in the game world, there was no need to tag them good or evil.
