I was just notified that The Witcher: Enhanced (along with Witcher 2) were just recently updated. I was curious as to the nature of the updates, and if I should re-download before my next play-through?

As far as i know there are no new updates for either game .
The last update for the witcher was for the Mac version and for witcher 2 was the Chinese update for the 3.2 .

Unless the update from the "My Account" page is to what you are referring to would be some additional content was added

really? additional content? like extra quests and stuff? That would be awesome.

I think that is what I am referring to, it said "update" on witcher and witcher 2 when i went to my games page.

No, by "additional content," Tommy meant those famous GOG extras, like the calendar and interviews with the developers and the art book and stuff. I think they changed the art book to a higher-definition version recently, so that might be the update notice you got.

The Witcher recently got some extra bonus content (er, should probably point out the calendar is NSFW XD)
