In a sense I hope so too ... but I would bet money on the fact that Larian will give us a range of difficulty options at some points, seeing as they mention the topic of difficulty in the Early Access FAQ. Although which options will be included, I don't know. Also, while Solasta is building/releasing these options right now, Larian's FAQ seems to indicate that they will do this at the end and it won't be available in EA.

As an aside : Wow ! It's not so much the impressive level of flexibility that strikes me. It's more the fact that their news section shows that Tactical Adventures seems to publish a communication about 2-3 times a month ! Baldur's Gate 3 is my first time going Early Access on a video game, so I have no real reference point for what is typical. But TA is doing what I imagine/feel a video game dev should do. I'm still not sure if I'll take part in its EA, but my enthusiasm for Solasta has just gone up one level.
