So, what is the difference between The Witcher 3: Wild Hunt and The Witcher 3: Wild Hunt Complete Edition?
I bought the W3 Complete Edition on sale sometime around Christmas, didn't had the time to play it, after a while I forgot all about it.
A few weeks ago I saw a sale on The Witcher 3: Wild Hunt so I bought it. Again? Usually when I own a product a message shows up informing me that I do own this particular product, but, no message appeared and I completed the purchase.
Yesterday while browsing through my games library I saw two listings for Witcher 3 in my library. One called The Witcher 3: Wild Hunt and another for The Witcher 3: Wild Hunt - Complete Edition.
So is it the same game, the one being with all the dlc and the other just the base game, or is there some other difference?
If it's the same games, minus the dlc, did gog let me buy the game twice?
I would appreciate an answer, please.

The Witcher 3: Wild Hunt is the base game while the he Complete Edition includes the base game + the DLCs. You should refund the base game. I have no idea why GOG let you buy it twice but I also wonder why you decided to buy it?

In the library in general it may still show both games(even after the refund). I too have 2 instances of the game

Thank you so much,
I thought this might be the case.
