The Paradox Interactive website has a page showing that they're going to be releasing more in-depth information about various game mechanics every Monday from now until mid-September, so it looks like we're going to continue to get a steady stream of new information from this point forward.
Each week's feature highlight is going to be about a different topic, with this week's topic being the one that's probably the most relevant one for us:
Road tools!
A lot of the information in the video and associated blog post is stuff that we already know from the trailers, but there's some
really cool new stuff, too. The things that I'm most excited about are two things that I was really hoping for but never actually expected to get: Roads that deteriorate over time and have to be maintained, and traffic accidents! I was already really excited for Cities: Skylines 2, but now I'm even more hyped!
As a side note, it seems that the new feature highlights are posted at 9:00 AM central time, because the video was in the middle of live streaming when I checked the page a few minutes after 9:00 AM.
