New buildings look like an art project by someone on hallucinogenic drugs rushing to use up all their left over paint before the monsters get them. Also functionality right now has some issues... and game realism is killed by magical service points (when they bother to work).
A few problems have been reported on this including some I've seen myself where garbage isn't being collected at all for certain buildings when others around them are fine (zero mods in use - see my edit at the end, more and more bugs now)
I also had an issue with buildings being spawned on odd bits of grid behind other buildings so they had no connection and complained about services.
The bus expressway roads added to the base game have issues and break pathing (not strictly a DLC issue but worth noting).
I really don't think this had enough play testing as I encountered these problems pretty soon after purchase just starting a new city.
Bear in mind the base game buses really won't do the job if you want a big pedestrian area with buses moving people in and out of it. Vehicles CCP or workshop buses for higher capacities are a must
You also really want some form of car parks at the entrance to the zones unless you want a long line of residents' cars on the road. The solution, either workshop car parks or CCP for the mid-century modern car ports which are a nice visual match with service points (the sad reality of Cities: Skylines, the solution to a problem always seems to be DLC).
There is some good stuff like the new bus and metro stations and walkable areas do move the game forward more than any other DLC and will massively reduce traffic. Beyond that I'm feeling a bit negative about it after looking forward to it since it was first previewed.
The service points don't make much sense and kill any challenge or management of planning a city. You can put them pretty much anywhere and they just take care of everything across massive areas far away - all deliveries and garbage dealt with in an instant. You just need one road to deliver goods to them. You can even make industrial areas pedestrian which makes no sense. Ore trucks, oil trucks, forestry trucks? they're now invisible.
According to the official livestream there's "underground tunnels" that handle trash and cargo. What? Does it all float along the water pipes somehow? It just doesn't make sense. In real life you have service roads to buildings, out of hours deliveries, etc. Here, you just plop down a Mary Poppins service point and everything just sort of invisibly comes out and deals with everything. The service points are a lot like the game's monuments.
I really hope they do something with this like limit the range a lot because it takes away all the thought process of building something functional and realistic.
Mainly, I just don't get the design at all. The workshop is full of assets to create 'real' cities - it's what people want and you're just not going to get a realistic look from this pack. In small doses these things work but I don't want an entire city that looks like the sparkly unicorn rainbow statue from natural disasters. There are four new policies with one that leads to people stealing candy bars. Bizarre. Is this Roblox now?
When you see the two CCPs also just released which are classic, classy looking buildings you wonder what the thinking was here. I assumed when buying this there would be some more subtle options for realism that blend with other stuff. Sadly not, this feels independent of the existing game. There really should have been a few style here to choose like 'old town' 'modern' and 'horrendous art project' - instead all you get is the latter.
Thankfully you can ignore these buildings and just make pedestrian areas with existing assets (e.g. Green Cities specialisations work well). But that's disappointing because wall-to-wall was one of the big selling points for this and you still have things like the high-capacity schools which are useful but stand out too much.
Like a lot of other DLC it feels tacked on and has no integration with other DLC. You won't get neat integration with your tram lines, park area, campus, bike lanes, etc. Stuff like harbors and fishing with a built-in bit of road can't attach, nor can you have a post office so you're forced to mix and match.
A few youtubers like City Planner Plays have gone through the pack and highlighted the lack of integration I mentioned so I would recommend taking a look before you buy what is a relatively expensive add-on.
I would say hold off buying now, wait for the bugs/service point range to be fixed and some nicer, more realistic wall-to-wall buildings to find their way into the workshop.
Then, if you want something anywhere near to realism wait and see if the magical, fantastical service points get toned down at all in an update. Right now they are like a cheat mode.
Basically, if they completely fix almost everything it will be quite good.
Edit - after further time with it. I don't think my review is harsh enough. There are un-fixable bugs with the service points which seem to be completely random. I've got an area where buildings constantly abandon because they cannot receive goods no matter how much industry and cargo capacity I provide.
This is truly terrible and I'm annoyed my refund request was turned down.
