Weird. It's like the combat designer does not need to know how BG 1 & 2 played, since BG3 is in a new engine, with a different system (TB instead of RTwP).
What, at all, would the Senior Combat Designer take away from two 20 year old games that would work in this new one?
Story designer: Sure. You want the story to feel like the proper tone for BG.
The artists working on the cities and such? Yeah! Gotta make sure it looks like a BG game..within reason (graphics were allot simpler 20 years ago)
But combat? That is the least-needed thing to take away from BG 1 & 2.
It doesn´t matter what position you have at this project. If you don´t have a clue what the name and the game "Baldur´s Gate" mean then you are the blind man who speaks of the color. Then you can’t understand what the others are talking about and you don´t have any passion of making a Baldur´s Gate game.
I'm not saying that you can't make a good game without playing BG1/BG2. But we are not talking about Divinity III or any other game. As the name suggests, Baldur's Gate III (PART 3) we're talking about a SUCCESSOR. I find it questionable when someone who has not experienced the magic of Baldur's Gate makes profound decisions (the combat system is one) about a successor.
