Okay! Time for a lengthy post on my thoughts:
Engineer: The on play effect seems fine, I'll probably trash it after a few plays. The 4 debt cost is what intrigues me. It's so small it seems like it is essentially a 4 costing card. My guess is the debt cost is so it can't gain itself. Don't know why that would be too good though. I do appreciate having a wider variety of debt costs. The art seems decent, especially for a first time artist. Interesting that it features a woman, don't know what to think about that. There do need to be more cards with women but I would have put a dude on engineer.
Overlord: BoM 2.0? Never saw that coming. I don't like how it's such a good opener, I do like the interaction with highway and such. I'm glad this skips the clunky wording of BoM. Man, I still don't get BoM's wording. More great art from a new artist! The pics a little low quality but I like the look on his face.
Encampment/Plunder: Encampment seems great. Reminds me of Co0kiel0rd's Building Cranes and Asper's Alley. I.e, a one-shot that returns itself to the supply. I wonder why it sets itself aside instead of going straight to the supply. I appreciate it mentions plunder, that's what I want in split pile, more on that in Patrician and friend. Plunder seems great. My gut tells me it's way better than Harem (And with better art to boot!). I don't like the art on plunder. Encampment is good enough art put plunder has the same problem of fortune, it just doesn't say "Plunder". It needs to focus more on the treasure, not just some gold crap against a dark background.
Patrician/Emporium: I like the simplicity. Even with all the newfangled debt and landmarks and complicated rules you have easy things like forum and emporium. Patrician seems weak, I'd buy vagrant over it. Thanks for having the right wording on this *cough* Envoy *cough*. Emporium seems nice, but I wonder if it's ever worth buying one of these without the VP bonus. This seems like a nice low-key pile. Not an insta-buy (Page, Ambassador), not a niche card (Adventurer, Counting House). Now what I hate: The cards don't have enough synergy. Sure patrician guarantees there will be 5 cards for emporium, and emporium is 5 for patrician, but these would have worked on plies by themselves IMO.
Sacrifice: Great card, not much to say. I like the essential bishoping of estates, and the interaction with ruins. Here's my biggest complaint: What the heck is up with the formatting? There is like a mile of spaces in between the "Action Card" and "+2 Cards, +2 Actions". Why? Doesn't seem consistent with ironworks.
Archive: Great card, I hope we get more 3 turn durations in future expansions. Not much to say, other than it's not Archivist, there's already a fan card named that and it's a pain to rename them.
Charm: Awesome card! I like it better than HoP by far. I thought the +Buy wasn't supposed to be bold though. Wonder which effect would be used more. I'm leaning twords the second but I think the first will be better many times. COMBO: Charm/Tournament/Prince: Solve that age-old problem by letting you get the prince AND the province at the same time!
(Yes I know it's not that good) The art/name seems a little confusing. No doubt it will be clearer on the physical card. Charm is a stretch, but hey, we're running out of names.
Forum: Yeah, simplicity. Nothing to say about this, it's pretty boring. The whole "Holy Crap, Insta-pie w/highway" thing was shown with Villa, so nothing to say there. More art by Ryan Laukat!
Legionary: Killer attack! This seems like a phenomenal card, a terminal gold is great for $5. Tenatively, this seems better than Maragrave. I'm a huge fan of the art.
Wild Hunt: Ghost card, Yes! I love the name. But NOOOOOOOOOOOOOO! It doesn't put cards on top of your deck! The theme is ruined! WHY?

??
It seems a bit weak, but smithys are good. The artist really nailed this one.
I'll cover the events and whatnot later.
