I really doubt that the licence would be exclusive, I suspect that any AAA type game will be set in the Realms and there will be some kind of BG3 successor, but I really cannot see Tactical Adventures Franchise doing a AAA type game, much less a BG3 successor.The survey they have up for the 2024 announcement asks what people want to see as post game content and one option is “adventures in the forgotten realms.”
Are they hinting that they may be getting the license for FR games?
So, maybe they can get a licence and I think it would be smart of WoTC to give them one. I would expect to resulting game to be more polished version of Solasta.
I do hope they can afford to hire some better writers though and some more artists, a greater variety of faces in the cut scenes would go a long way. "Stay in the Light".
