Well... Let's be honest- whatever devs say, comparision between promises and reality look... Not too good. Let's see (all stretch goals from Kickstarter were supposed to be in game actually):
(from "cheapest" to most expensive)
1. Bigger, better, etc. (basic goal): well, we don't really know what would it look like without KS, so let's say it's in
2. Homestead at the end of time: in (but for me it looks rather boring- I mean it looks amazing, but there's nothing interesting to do, with trader showing after gathering half star stones...)
3. Personality and talents which influence various interactions: only talent that actually seem to influence anything other than combat is pet pal. Anyone seen personalities?
4. Kirill gets his own orchestra- in, but half of music in game is either from Divine Diviniy or Divinity 2 (it's best in-game music I've ever heard, but it's still nothing new...).
5. Henchmen become companions: I've only Jahan with me (plus generic thief) as companion, but he's hardly most immersive companion. Hell- he doesn't even seem to be bothered by fact I'm striking a deal with Moloch, even though he's happy with imp slaughter...
6. Day and Night, Npc schedules, weather system: no, no, weather is static or changes unnaturaly fluently from storm to firestorm (Cyseal).
Plus:
Lair beneath Phantom Forest, 11 levels: apparently not in-game
Bellegar encounters, 5: I've met him only once, but I hadn't finished game yet.
All-in- all, only two stretch goals are fully implemented ("bigger, better", homestead) three are entirely not in-game, one is partially in (old music- while great- is played as often as new one).
