I agree with @GM4Him that this might drive D&D players away, and they are far more numerous than DOS players, that I believe would've bought the game anyway just by being TB.
And yet WotR has been getting steadily lower in player chart numbers, might be below DoS2 now, even though it's only few months after the release. Solasta remains a niche game. D&D players might be numerous, but how many of them are gamers who buy computer gamers is what matters.
To be fair, "decreasing player chart numbers" (assuming you mean # of players that play concurrently/each day) isn't a great metric of how well a game has sold. WotR isn't multiplayer or releasing significant new constant, so it's expected for the player count to drop.
I agree with your last sentence, but I doubt any of us have reputable data on that... There was a survey on this forums way back that I think showed ~70% of BG3 EA players were familiar with D&D 5e, but of course forum users are a biased sample and "% of BG3 players who play D&D" is not the same statistic as "% of D&D players who will play BG3." This is yet another thing that'd be super interesting if Larian put on an official pre/post-EA survey and then released that data. And like one of the only valid reasons for a dedicated BG3 launcher - to advertise for and link to that survey.
