To be fair guys, if someone want light-hearted adventure set in Pathfinder (i don't know this setting to well, but i think DnD is more mature) then Kingmaker is really for him.
But if someone want more toned experience set in something that resembles of oldschool DnD games like Icewind Dale or Baldur's Gate - then PoE is for him.
I would say, that, that light atmosphere of Kingmaker was such a turn off for me. I was really hyped for it, i still remember waiting it to come out from kickstarter; but now i couldn't bother less about it. It is much more shallow game than i expected it to be - but maybe my expectations of it were too large. World felt shallow, setting was something uninteresting (much more than PoE, which had at least lore presented to you on start), some characters were just, i don't know, like from some jRPG? For example this orc and Olivia (as far as i remember) who were some threesome couple thing. Oh yeah, but that the sex part - the most sad thing was, that as powerful as they were when rescuing them, you just could see that they were some teenage wannabe heroes of century, where in PoE you had characters that felt much more real in that regard. Eder is a perfect example, but there's Durance, Mother, Aloth (i liked him, because he was a type of a guy like a Virgil from Arcanum).
And on the other hand, you have Pillars of Eternity - Somewhat grim setting, more linear (i really preferred first game in that, second was an interesting idea that fell flat imho) with a more adult content, less nuances like threesomes or whatever else there is. And damn, even if it's on unity, graphics are really on point capturing that. And coming back to linear part - it was really nice way to introduce you to world; camping at first, then discovering some things, then working your way up from small village to big cities). I really hated how Kingmaker played that out.
And there's gameplay, but that's not the topic about it unfortunately.
