Slow down kiddo, and consider that the actual D&D rules are so restrictive that they don't translate well into a computer game if done completely literally.
that counter argument is void since solasta came out. it shows, how perfectly the dnd5e rules translate into a crpg. and how many special things can be done.
if you combine all the ideas of solasta together with bg3 ideas (but toned down area stuff), it would be such a perfect gaming experience.
so many things you could try and do.
but well. it's 2020. that won't happen...
