I heard map and dialogue making were axed by Hasbro. They don't want modders making free expansions or stories.
That's the rumor however Larian has fumbled this entire situation so badly it makes me think it's actually a mix of Larian's cosmic levels of ineptitude, and arrogance after winning so many awards.
For starters before the game released they said they'd support modding. People were already figuring out how to mod the game before this as it ran on the same engine as Divinity Original Sin 2
Then after launch CEO Swen says that there'll be a toolkit releasing after the PS5 port in September. He also does an interview talking about how the toolset is really raw and that anyone who wants to use it to make something will need a team of developers.
Then they just stop talking about it until earlier this year when fans started continuously asking them about it. They finally said they were working on "cross platform mod support" as if anyone asked for that bullshit. They refused to answer anything about the toolkit.
Then they decide they're abandoning the game and they're not going to release a dlc. They also say they're not going to work with Wizards of the Coast ever again. Swen changes his tune about the toolset and says "nah the toolset is shit we're not releasing it" and says "we're not a tools company" as to why. Saying that his tools are shitty and nobody should use them. Also they wanted to focus on things supported by the cross platform modding support. Because Sony refuses to let them support mods with custom assets.
Then this toolkit releases and it just does shit that was already figured out by the fan community months ago. But half of it is disabled and easily re-enabled within days of the toolkit's release. And now they're banning discussion of it. The toolkit itself is indeed busted as some of it doesn't work out of the box. Like you can't save dialogues because it relied on a translation server they would get automatically sent up to. And according to some of the people working on fixing it, it would've taken an enormous amount of work to properly strip the editor of all of its functions because of how layered all of the features are.
It's just at every avenue they keep giving us cagey vague answers to direct questions. It's like they're allergic to giving basic yes or no answers. For some comparison CDPR said earlier this year that a toolset for The Witcher 3 was coming out this year and then 5 or so months later it drops and it's peak.
