Wow, thank you all for the feedback.
So basically you are all telling me I need to see this game as a seperate game that only takes place in the same world. That makes me a bit sad, not gonna lie, but that's what I already thought it would be.
The thing is, as some of you already said: In BG I got attached to the characters. In DO:S not at all. I don't care about them and that is sad, because it is a RPG after all. I want to get to attached to the characters, to their stories. That is one of the most important things for me.
I also think the world in BG felt more alive, like you would enter a city or a village and a random guy comes to you and tells you to come with him and you kind of have no choice but to follow him and just things like this.
Some of you said that BG3 is a bit like DA:O, which is also one of my favourite games ever (at it's time it felt like a BG sequel in a different world). When I saw content on youtube and a bit of the cutscenes, it actually reminded me of DA as well. So that's a good thing.
So do you think it's possible to love BG3, if you haven't loved D:OS 1+2, even if it's so similar?
Is the combat also just about the elements (fire, poison, etc.) or are we getting also spells, that were in the old BG games?
