I see zero reasons to use DND in an action game. The world of Faerun a collection of bad fantasy tropes with a few good ideas. The only thing that makes it interesting are the mechanics. Maybe Eberon but no one really likes Steampunk...
I highly doubt that there is demand for such a game when there are better fantasy IPs with more unique ideas.
The Forgotten Realms has been a very successful setting for decades now, many fantasy settings would be lucky to have its success and depth. The Forgotten Realms is a great setting. Damn heretics 😋
