I always find it irritating when such lists totally ignore the many fine adventure games of Daedalic.
OTOH, I do get some satisfaction from the fact that their newer, non-point-n-click style games have worse numbers than the more traditional ones. (Obviously, they haven’t been out for too long yet).
Anyway, here’s the data:
|The Whispered World Special Edition
|Edna & Harvey: The Breakout
|Edna & Harvey: Harvey’s New Eyes
|A New Beginning - Final Cut
|Chains of Satinav
|Chaos on Deponia
|The Pillars of the Earth
Deponia seems to be a bit of an outlier. Did they give that away for free at some point in time?
It’s also worth noting that quite a few of those games were sold DRM-free on DVD, back then when that was still a thing. So the numbers are likely not indicative of overall sales. The exception to that is Chains of Satinav, which always required Steam, even for its physical copy.
