Why they said that their changes to D&D are needed for the video game environment when Solasta proves that this is not the case.
Well based on Steam sales info the BG3 EA has:
sold 10x the copies of Solasta
has double the average playtime by the players who have bought those copies
has a 32 times higher all time concurrent playerbase
has 35 times the peak players in the last 24hrs
So basically, when they said that, they were using the good old Obi Wan Kenobi "point of view" perspective of what constitutes a successful and profitable product for them as a production studio.
