I see the 'this isent baldurs gate' complaint so much and noone can voice well why they think it isent a baldurs gate game.
Let me try to voice it then (although after being very disappointed with the prologue, I like the game more and more. It is slowly becoming a Baldur's Gate game).
They haven't tried (yet?) at all to give any sign of it being a Baldur's Gate game. The engine, mechanics, and even the first landscapes, are 100% Divinity:Original Sins.
But to me, Baldur's Gate isn't mechanics, it is a spirit. And when we progress in the story, this spirit, mostly based on companions interactions and landscapes, seems to come out.
Why don't they give us at least a little wink, to let us know we are in the right place, from the start? A lot of nostalgic people, seeing this prologue and mechanics, will just give up and look no further.
Maybe start the game in one of BGs iconic locations? Or a quick chat with an NPC from the first games?
An example/idea:
Intro video: you start in a very classic medieval tavern. Owned by a retired adventurer, a big, strong, bald guy. Strangely, a fat hamster is sitting on the counter, but hey, we've seen stranger things.
Then all hell breaks loose, the tavern is attacked, you get kidnapped and wake up on a strange ship full of brains.
Game starts here.
See what I mean?
Short version: this isn't a Baldur's Gate game because it doesn't try to be, at least not at the start.
They are going to make an awful lot of money out of nostalgic veterans, and they took over probably the most famous RPG in video game history. An acknowledgment of that would have been nice.
