As to why or how, again, perhaps this is due to the nature of GWENT and trying to balance difficulty once the sheer variety and number of competing strategies and decks come into play. Whatever the reasons though no doubt it comes from creating an RPG story-driven game unlike anything else out there. One that features one of the best interactive bits of fiction this side of The Witcher III – with a flawed, interesting, and awe-inspiring protagonist in the form of Meve. No doubt, we can't wait to check out the next Witcher Tale.
Whether or not this stance too critical of the deep and well-executed combat, well, who the duck knows? If the idea of a hardcore XCOM-like experience in a post-apocalyptic mutant world sounds enticing, then, hey, this is essential.
In the end though, perhaps what sets apart Project Warlock from the very recent old-school shooter renaissance we've been seeing is that outside of inspiration and certain elements it doesn't look any one thing from the '90s. Which in the end makes it special, and something well worth checking out.
