Well, it sold well .... for an indian game. It is considered one of the best cRPGs of ... modern years, because there is really nothing for the past 10 years.
And those 2 arguments are too fallacious. I am yet to understand all the buzz about DOS2, except it came out from a very sterile era.
There were tons of good CRPGs that came out in this new renaissance era of CRPGs.
Wasteland 2 Torment Tides of Numenera Shadowrun Returns Shadowrun Dragonfall Shadowrun Hong Kong Pillars of Eternity Pillars of Eternity 2 Tyranny Masquerada Pathfinder Kingmaker Divinity Original Sin Divinity Original Sin 2
To the best of my knowledge, DOS2 sold the best out of all of those. By a wide margin, even.
CDPR is currently the only studio that understands how immersion is central to a RPG. They really mastered the technique.
And yet the combat in their Witcher games is horrendous. CP2077 seems to step up the game though.
