I think it's a great D&D game, and I've played almost every D&D video game ever made. Sure it has some adaptations, some house rules. So do I, when I DM tabletop D&D. I usually use more house rules than Baldur's Gate 3 does, and my players never say "this isn't D&D".
Not to be rude to you, but if you did that i would say something.. to much homebrew ruins the game.
It can ruin the game, or it can make it better. Depends on how good the DM is. It's not like the system as designed is perfect, especially given the variance of desires of different groups.
