Hello again! I posted Polis here a while back and wanted to show you how it's coming along.

The biggest changes are the visual overhaul and being able to play the same city interchangeably in 2D and 3D. You can build in either view and switch back and forth when you like.

I've spent quite a bit of time reworking the buildings, neighborhoods and the details around them. Some of you felt the original was missing a bit of character, so I'd be curious to hear what you think of it now. I've included close shots in both views so you can see the details.

I've also been working on the economy and upkeep. The comments last time about money being too easy were fair. There are changes to how neighborhoods grow as well, and you can now upgrade existing power and water facilities.

It's still free, works on mobile, and runs in your browser. No signups or accounts needed. Once you've loaded it online, you can play fully offline too.

You can play it here.

If you fancy giving it a go, I'd love to hear what you think. Any feedback is welcome, and thanks for taking a look!

Hi everyone — I put together this free interactive resource for exploring cognitive biases and related effects. I thought it might be relevant and helpful here.

https://thebiasmap.com

It’s adapted from the Cognitive Bias Codex, with 188 entries, plain-English explanations, everyday examples, sources, and short animated videos. Credit for the original Codex is on the site.

I’d appreciate any feedback or corrections.

Like a lot of you, I grew up on SimCity. A few months ago, I started building my own city sim in the evenings to scratch that itch, and it's deep enough now that I'd love feedback from people who actually know the genre. It's called Polis.

It runs entirely in a single browser tab — no install, no account, no patch day, no 40GB download. Click the link and you're the mayor. It's free, with no ads, paywalls or microtransactions, works on mobile (you can Add to Home Screen and it runs like a native app), and the whole thing — simulation, procedural art, generative music — is one self-contained file running on your device. Cities autosave locally and export as a portable save code.

It's not a toy, though. The systems you remember are all running honestly underneath:

• Real RCI economy — population, jobs, commerce and industry chase each other through supply and demand. Crank taxes and growth stalls. Every number is connected.
• Buildings that grow themselves — zone a block and lots level 1→7 on their own; four mature lots then merge into a tower that can climb to skyscraper, highrise and megatower.
• Traffic that bites — cars actually drive your roads, follow each other and yield at junctions. Narrow roads gridlock, gridlock chokes land value and growth — so you fight back with avenues, buses and elevated rail.
• Networks to plan — roads carry power and water through the whole grid, so a building just needs to touch a connected road. Plants range from coal to solar to nuclear to fusion, each with its own reach and smog.
• Read the city like an X-ray — overlays for traffic, density, land value, pollution, power, water, crime, education and health. Every problem is visible before it hurts.
• Govern with trade-offs — tax rates, funding sliders, loans, and ordinances (recycling, curfews, festivals, tolls), all cost-vs-payoff.

For challenge there are six authored scenarios, each with a goal and a clock — a tutorial village, a collapsed housing market to revive, a citywide blackout, post-earthquake rebuilding, a flood plain that floods every other year, and a no-loans "Iron Budget" gauntlet. Difficulty runs Easy → Normal → Hard → Very Hard → Kobayashi Maru (exactly what it sounds like). And if you'd rather watch it burn, the disaster menu has earthquakes, typhoons, floods, an alien invasion, a dragon, and a giant fire-breathing beast that stomps through downtown. Damage is permanent — save first.

Maps expand up to a colossal 256², and a single city can climb 12 ranks all the way to a million-citizen Ecumenopolis.

It's still a hobby project and rough in spots — I'm actively tuning balance. What I'd most value: does the core loop feel good, where does it drag, and what from the classics do you miss?

Happy to dig into how any of it works in the comments.
