Maybe the fans of the old games are not the game target audience anymore for reasons known by the Sales department. I mean, they are using D&D5e Assets, they are advertising modules of WOTC together (Descent into Avernus, etc), they are doing interviews together with WOTC CEOs, working with D&D5e creators, using the ruleset and the setting...
But I dont´remember them referencing the old BG games in any interview unless asked first (In one interview even Sven Vincke and Mike Merle didn´t remember the canon ending of the baalspawn crises), they didn´t make videos of "Sven Vinke playing the old bg games", didnt´hire any of the original game screenwriters, musicians,... didn´t use images of the old games and characters to advertise the game (Owlcat, for example, included two of the iconic characters of Pathfinder in the videogames, Amiri and Seelah),... didn´t take people from Black isle into the game-cons,... and they do none of the things that the PR department use to do to rally the old game fans.
Just food for thought.
Target Audience by priority IMHO.
D&D 5e fans
Forgotten Realms fans
Divinity fans
TBRPG fans
Traditional Baldur's Gate fans.
As both a 5e fan and even more so an FR fan and a TB fan its shocking to be in the target demographic for once because that nevet seems to jappen to me.
