There’s the Trilogy Bundle, which is not a great deal right now, since the GOTY version of The Witcher 3 is discounted to the same $19.99 price as the base game in the bundle. So weighing that 10% off vs GOTY version, I would rather go with the GOTY version, both are the same price right now individually.
Since I am pinching pennies right now, I might just buy 1&2 for now… wait for a even better deal on 3… Unless someone here tells me not to…
Sale to end April 15, 2018.
Edit:
Thanks to @Agzer’s post below, apparently you can get the first Witcher game free on GOG, if you use the client:
I own the Witcher 2 but I couldn’t get into it, the combat was just too darn weird, plus I had began my first gaming depression when I got it for free from Xbox Live Gold.
I hear the Witcher 3 is a massive step up in its combat but you really should play the other two before hand for the story, so I am told.
I would suggest the GOTY Edition of Witcher 3 as it has those two massive expansions that are bigger than most games. I wouldn’t buy the base game alone.
I’d listen to this guy’s opinion on them, he is honest, although a fanboy of the series.
You claim gwent and then on gog client when you go to your library click on gwent and then there will be a banner with witcher 1. Should i link you a video?
So despite what I said, I just downloaded the GOG client, since if I can play the first game for free, why not just buy the second game… Now how do I get the first game for free? I am quite lost… Do you have to be logged into the GWENT web page?
EDIT:
Nevermind, I found it… a bit convoluted, but a free game is a free game, I can’t complain!
So even better that I get it without any using any real coins. I did just buy the second game on steam, with anticipation of buying the third at a heavy discount.
I’m on phone so maybe that’s why
Now how do I get the first game for free?
