I would thoroughly recommend Divinity 2, but it is a very different game: it's a third-person, real-time combat game, not an isometric, turn-based strategy one. Speaking personally, it's my favourite of the series but YMMV. So in terms of gameplay it's quite different since you play as one character (though interacting with lots of others, of course) as well as the aforementioned, but it still has Larian's lore and humour and stuff.
