Community expected something with original saga vibe, not original saga technology.
And exactly what that vibe is is subjective and individual.
Yes, it is, in some way, but:
- Baldur's Gate community reactions are divided about that they liked what they saw or not, but there's consensus in case that the gamplay doesn't have any Baldur's Gate vibe.
- Let me show you an example. Heroes of Might and Magic 3 and Disciples 2. Both are turn based strategies with more or less similar rules (I mean there are differences, but I guess you know my point). Both of them have their 3d sequels (HoMM with number 5, Disciples with number 3). I bet you see the mood differences in those sequels although it's subjective and individual.
- of course those vibes and general mood can be felt individually, but If most of the community agreed that the soundtrack (I mean this part we heard in gameplay) is closer to Divinity that Baldur's Gate, UI is closer to Divinity and general graphic design (even character creator) is closer to Divinity, then maybe we can assume, that Baldur's Gate 3 (at this stage of development) has more Divinity vibe than Baldur's Gate vibe?
- just for example Justin Bell show in Pillars of Eternity how to catch classic infinity engine soundtrack mood without copying it.
Let me ask you a question: what's your feel about what you see and what you know? What in this gameplay looked more Baldur's Gate than Divinity DnD edition except DnD mechanic's of course?
