.... despite Wizards of the Coast being the ones who approached Larian to create it, while also having huge impact on its development process, lore, and overall story arc.
Dear Noraver!
Wizards of the Coast (WotC) is a publisher company who specialized in fantasy and sci-fi, which is for now a subsidiary of Hasbro! (and I have no doubt they have a great lore about marketing)
The world's The Forgotten Realms's (and it's lore's) authors is the novel writers from the very start!
Congratulations on understanding how businesses work. That doesn't change anything about my comment.
It's a fact that Wizards of the Coast has the final say over everything within the franchises they own and/or manage. This includes both novels and games within the Forgotten Realms setting.
Wizards approached Larian.
Wizards was involved in the process of the storyline.
Wizards approved of the final product.
By your logic, Wizards isn't worthy of its own creation.
You're either a very poor troll, or someone so very disgruntled about nothing but a title, and stuck in the past. Perhaps you should stick to just playing Baldur's Gate 1 & 2 for the rest of your days.
