Divinity: Original Sin Enhanced Edition is a completely separate game: not an update to Divinity: Original Sin. Both games will remain available on PC and Mac, and it is important to note that they are totally different entities, so if you've already bought Original Sin you'll see separate listings for Divinity: Original Sin and Divinity: Original Sin Enhanced Edition in your Steam Library.
Exactly how different are we talking? I bought D:OS but have been too busy to be able to play through anything but the first hour or so. Is it worth my time to play the original, THEN the enhanced edition... or should I just wait and play the enhanced edition for my first full playthrough?
