Larian Studios Forums Baldur's Gate III Baldur's Gate III - General How much is same as 5e? And is there a GM mode in the future?

I cant wait to create a custom campaign in this; and of course to be able to use the 5E rules in this. But i expect there to be some differences in f.ex the type of spells and abilities to translate into the game:
Is there certain things "not present" or other things hugely changed?

And is there actually talk as topic says; about a GM mode like Divinity in the future? ( i assume it has a map creator then)

and lastly

Please let the character creation be a bit "sandbox"; so we could add weapons/armor from the game and such to add a custom made character in the future to make littarly a character gallery for the tabletop/Pen and paper game.
