It adds another layer. What it adds is varied, and you can either be …
Choose a mild one with work bonuses, and be “oh easy, helpful”. Or …
Go random and get a tribal start that gets mad if you mine, gets mad if you gut a tree, gets mad if you slaughter an animal (hunted or raised). You can plant, but the random map has 20 of 60 days as a growable season. Right, so I build a shelter how? Eat what? The tribe does like other ideologies so …
Let’s have some random capture who joined and LIKES mining and cutting down trees do the mining and cutting. NOPE. Half my guys were all “I saw that!” and blew their moods anyway. I got the place established with much drama, and because my cook was a psychopath.
Beware: farmed animals, even without an ideology bonus, breed like rabbits now.
In other saves, still as Tribals … my dance parties are boring. And this matters! Gah.
New features and release is very mod friendly, since, like Wildermyth, many items have tags. The ideology set up allows you to include/exclude many things via tags. And the pawns care. Converted a warlike punk captive to my rustic ranchers and the first thing she does after joining is ask for her mohawk to be cut and to erase the death metal like tatoo. It mattered to the pawn. Both hairstyles, the old mohawk and the new do were added via mod, but one was tagged “punk” and the other “tribal”.
I don’t run any of the full conversion or big race adding mods. But it is nice to see it play well with mods that expand existing systems. This includes food/drink/drugs. One puritanical tribe got mad at a new hire drinking coffee! Not burn the place down mad, but how upset pawns get when a rule is broken is settable when you set up the ideology. I recommend going for lightest penalties until you see all the interactions.
And the “War on Killboxes” continues. One possible choice is “Hates turrets”.
Also, caravanning is more important. Pack animals/speed revamped, too. More events now take place on nearby spawned temp sites than before. Still fiddling with the choices and getting Tribals solidly established, so not done much of those new ones yet.
