D&D exists for about 45 years so yes, it's a bible and it looks like the 5th edition is really appreciated by role playing players. I trust them and I'd lobe this game to become a true BG and D&D experience.
I didn't realize all of those players were still playing the unaltered first edition, I guess it really is hard to improve perfection though.
BG 1 and 2 started from the table top rules and adjusted as was *necessary*. They became two of the greatest RPGs ever made, to the point where a major studio is making an unbelievable popular sequel 20 years later.
BG 3 is starting from DoS 2 and incorporating the bare minimum needed to make the game sorta seem like a D&D game, but in name only.
The rules of 5e have 6+ years of playtesting to support them in addition to baked in added content. DoS 1 and 2 were great and fun games, but their balance was laughable, to the point of being meme'd into the ground. If you think you can design a better rules system for an RPG go right on ahead. But there's a reason 5e has absolutely dwarfed every other RPG in the market.
