We absolutely need this for it to feel like a DnD game. Larian should also introduce 5e elements like bond and flaw.

Alignment is fun. The alignment grid has become a classic meme and is an essential part of what dungeons and dragons feel like, well, DnD. Just today I saw someone make a grid to mock some esoteric debate about military equipment.

"People will disagree / get angry" isn't a good objection IMO. People engage with / disagree with / get angry about things they care about. So if people are angry about something it means they are invested.

And this isn't just DnD, it the sequel to BG2 and theme of that game was: can you resist the evil inside; the BG plot was all about alignment. The bhaalspawn is born with a soul tainted by evil. Charname needs to decide which wolf to feed - will they embrace and nurture the evil inside or will they nurture their goodness?

Butt kicking for goodness!
