Personal Comments and Observations
When you boot the sim today - you’ll see a notification for Content Manager showing updates available for any content that was refreshed from UK World Update 1. That’s just stuff updated for UK WU1 if you installed it.
In addition - don’t forget to “Get” the UK World Update 2 in Marketplace, then you should see more content updates like the new 5 handcrafted airports. You’ll need to go back into Content Manager and install that update as well.
So that’s two sets of updates you should be installing today.
For the record, after I shaved off the non-interesting (to me) bits like Landing Challenges and Discovery flights, UK WU2 is just a shade over 10GB.
For the refreshed content in UK WU1, the footprint is just under 2.5GB for what I have installed.
These sizes may vary for you depending on what you have previously installed and what options you choose in downloading the new content.
