Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Changes in EA before launch?

Are there going to be any changes made to the EA game or all the changes are going to be made only on the final version of the game?

There will be updates and changes throughout Early Access.

See the interview: How Divinity: Original Sin 2 will evolve in Early Access.

Seems like the only thing that won't be changing during EA is our access to subsequent acts.

That's fine. Challenge-running act 1 is pretty fun.
