I remember back to the days of Neverwinter Nights 1 & 2 where there was a seperate program that allowed us to make our own adventures.
I looked into it and I can find only rumor and speculation when it comes to Larian releasing a similar module maker. Supposedly they released something similar for the same engine, but for a different game?
Do you folks think that we’ll get something similar for BG3?
Check out Solasta: Crown of the Magister. It’s another fantastic turn based 5e (SRD) RPG and it comes with a custom campaign editor https://solasta-dungeons.fandom.com/wiki/Creating_Campaigns
I really like Solasta and the small gaming team that created it. Hope they make more D&D games.
