I’m finding myself quite impressed by the North. Particularly, it’s clear a lot of effort when into balance as opposed to a kitchen-sink approach. I get the impression the adage of really better as opposed to ‘more is always better’ was wisely followed without forgetting any of the important parts.
I wonder if you’ve considered allowing residences with a capacity above five people? Particularly in combination with for example your Ironman mod, houses can fill up when the oldest children still have several years before they become students/laborers. Allowing families to keep growing with a capacity of say 7 people – with the structure being quite a bit more expensive of course – would be a good addition I think.
