Pillars of Eternity 2 sold somewhere between 500,000 and 1,000,000 copies, quite a few on sale. It significantly improved the graphics, performance, and writing over the original, and had more interesting gameplay overall. Itemization is noted even by some detractors, and that is apparently something Josh paid attention to. It is considered a financial disappointment, but probably turned a small profit in the long run. It received critical acclaim and has some fans, but niche RPG enthusiasts like Codexers didn't like it a whole lot for the most part. The systems were over designed and the content was obscure, but it might have a shot of becoming some sort of cult classic because of pirate motifs and because of sheer 'realism' in the old Elder Scrolls sense of the word, where the cosmos and world seem to have a real, detailed, in-world anthropology and politics that a setting like the Forgotten Realms couldn't give two shits and a Popsicle about. While you can argue this Josh-y realism in tone and setting came at the expense of adventure and fun, it does possess a certain appeal once you've acclimated to it.
Divinity: Original Sin has sold somewhere between 2,000,000 and 5,000,000 copies, and I'd incline toward the latter. It's a massive financial success (in the humble terms of the genre) thanks largely to the multiplayer feature that allows people to treat it as a couples RPG or a romp shared among friends, proving that Sven is some kind of genius who finally realized the type of thing Tim Cain talked about but was never able to achieve. It is also a critical and audience darling. Niche RPG enthusiasts like Codexers are ambivalent about it, but tend to be negative. Like Pillars of Eternity 2, it is a bit over designed, with systems that can be counter-intuitive (inconsistent rules, etc) for the sake of balance. It's greatest strength in its sheer interactivity, with seemingly limitless ways to interact with the environments and NPCs, including just slaughtering them all, and lots of things to explore. It is a sign of a certain kind of quality you can kill pretty much everyone in the game and still be able to beat it. Act III sucks though.
Pathfinder: Kingmaker sold pretty similarly to Pillars II, but probably less on sale. Even so, it was a modest financial success because it was made in Russia and not California. It's critically well regarded and audiences had fun with it, although not nearly on the same scale as Divinity 2. Niche RPG enthusiasts like the Codex tend to like it, but it has many detractors. Undoubtedly, it is the closest in design, tone, and style to the old Baldur's Gate games, with systems ripped from the tabletop rather than built from the ground up to take advantage of the PC.
