you approach this discussion completley the wrong way and thats why arguing with you over this is pointless.
you know what a 100% BG game is? BG1 or 2.
By the metrics that you apply. If a feature that is in DoS makes soemthing , percentually, more a DoS game. Then having a "proper" Baldurs Gate game by your standards menas an Infinity engine game.
So why should anyone listen to you. What you are talking about is bloody ridiculous.
