I am making notes about all the stuff I am not happy about but as a summery. BG3 feels like a great Forgotten Realm campaign but the DM hates D&D 5e rules so we are using another RPG system like Savage Worlds.
I am loving the world /story but you have to get past that it definitely not Rules as Written or Rules as Intended but a heavily homebrewed game system. D&D 5e in name only.
If I had to tell someone what BG3 is it a single sentence it would be:
BG3 is DOS but in the Forgotten Realms!
I was talking to my bf tonight about my disappointment and he pretty much said what you did.
"I set my expectations that this was a Divinity game in a Baldur's Gate setting from the beginning."
