The number of youtube and twitch broadcasts have helped my day at work fly by! I recommend the yogscast ( https://www.youtube.com/watch?v=YDcfppKeDmE ) or quill18 ( https://www.youtube.com/watch?v=3xJrQCAk9ZE ).
Honestly I love the change in mechanic for workers/builders. I think the new mechanic forces you to be more strategic about what improvements you make and when you make them. This works well with the new design of cities and districts. I was put off at first, but I think they have made it work well with the game’s new mechanics. Ultimately there is a lot more emphasis on city planning, development timing, and adapting to your environment (beyond simply what resources you have nearby).
Also, from both yogscast and a second quill 18 stream, the Vikings look like A LOT of fun in the early game chaos. Those longships are unstoppable.
