I'd play through the whole of Divine Divinity; you will find it's an enjoyable game. At first I didn't play it because I disliked isometric view games but I realise now after buying the game I made a stupid mistake - I enjoy it. To put it short the game world is more varied than Divinity 2 but I do find 3rd person game more immersive; the viewpoint really does make a big difference to me. The ability to turn into a dragon was also a big plus. As Kein said, there's nothing wrong with that though each to their own.
If this next RPG after D:OS and D:DC is Divinity 3 and it had a 3rd person viewpoint with the variety and richly detailed game world of Divinity then it would be ideal for me.
