In who’s opinion is this not like a d&d game ? This is a d&d game pure and simple.
D&d spells, setting, characters,magic items, rules, races, combat..etc
D&D games do not stop being D&D because someone adapts for a video game medium.
D&D games do not stop being D&D because there are some slight rule changes...( yeah yeah the surfaces thing I don’t disagree with that & many other comments people have) ... but declaring it’s not D&D is just utter garbage.
