What games are good for multiplayer base building action? What makes them work?

I usually play base building games solo, but I've had some fun playing with friends too. I'd like to take a look at some multiplayer favorites and see what makes them work well.

For context, I've played a good bit of Valheim and V Rising with friends. Valheim's construction system seemed flexible enough that you could get creative with it (V Rising less so), and I've been a part of some cool villages. One thing I didn't like about multiplayer Valheim, though, is that the lower level or newer players didn't seem like they had a good way to contribute. Their next task (in the game's main path), whether mining copper or iron, had been done by a half dozen people before that.

So, maybe my bigger question is - what base building game has done multiplayer well when players have a range of time to play? (I.e. Player A can put 20 hours a week into the game and Player B can put in 4.)
