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.
