Whether a phalanx (Socialist/Soil Party) Libertarian or a non-Commune Libertarian, you can appreciate Animal Crossing New Leaf, as the most Libertarian game and without any preaching. Much like Tales of Vesparia, although occasionally it preaches through the main protagonist a little.

But through actions you know the game.
Your a new Villager and your there because there is no one else willing to be the Mayor, they need to affirm someone who checked the Classified in God-knows-where. You have nearly no authority, you have 1 ordinance to pick from, you get no salary, you have to shake trees and sell fruit to pay off an interest free loan. The Capitalists are cool here, aside from the Fascinista atop the store. Brand bullies will happen.
You can put down public works projects, but it’s voluntary donation, no taxation. Take that Sim City.
Everyone is free to trade, and speak. The own their property, and okay some times make minor easements on the Mayor’s House. But yeah, speak. You’ll notice there is no safe space, there is something you or another Animal says to another Animal that will make them dance, have no major reaction to, or make them gloomy til the clock strikes. No one has a right not to be offended. But it’s all civil and non-violent.
No aggression. In fact some want to leave to wage a turf war.
Oh yeah they are free to leave, all be it easy to argue against the idea. After all why leave such freedom?
It has a old school Comedian, okay bad one, but he runs a night club, KK does his shows, no one is kicking him out for an offensive song.
Shampoodle is a strong business woman, but doesn’t talk about being one. As are the Hedgehog Sisters. Politics isn’t important earning those bells are.
In a sense your town is Trakken before the Master lands and your the Keeper. A crude comparison, but close.
A great classic Liberal world.
You have a border guarded, sure, but you can open it up and bring in foreign villagers and trade or give freely to them as visitors or as a visitor. Endless options for voluntary interaction. No adhoms anywhere. Unless you find the odd bad actor visit you.
Largely I have been fortunate, aside from one annoying kids from Australia.
Only weird thing is Katy traveling, I mean really where is this kids mother? At least a free society is likely a place where pedos are banished or locked away under ground. The cop doesn’t do much about flower theft, so who knows.
Utopian aspect of liberty, and the great escape in games, is this doesn’t exist or is punished severely.

I met a lot of people doing this through other people who oddly enough played Heroes of Ruin with. Most of the people were very good visitors. Although heard some stories, but you always remember the broken flower beads and stolen ones.
But you can remove them. Although I wonder if the Mayor changed his toon on liberty, seems he was banished from to an Island. Hope he didn’t touch Katie. But if you ever want to know what liberty is, play that game. Granted it’s probably purer than anything we will ever see in real life. But we can dream. Now you might say “see they are political,” but no it’s more a subconscious thing, likely, how someone naturally came to untainted by anything woke. It didn’t need to be preachy and didn’t need spell it out in words. It didn’t even have to tell you who to vote for, see above, I won fair and square. Even resetti, if you say “I don’t know” to him will lay off because he can’t prove it and Kapp’n ain’t getting #Metoo complaints, because he’s just a funny turtle.
