Kinda funny game, though if you want a bit more fidelity, but less control, Microsoft Flight Simulator has a pretty good version of SF. Though as for games that use SF (but not 1:1) Watch Dogs 2 is a pretty good proxy, though my favorite video game interpretation of San Francisco is from GTA San Andreas (San Fierro)

my first experience with San Francisco in a video game was through the City Escape stage in Sonic Adventure 2. and I didn't even know then that it was San Francisco (I had never been there when I played the game). only realized this when I visited the city many years later.

man what happened to loading bars? I'm sitting here watching the block bounce in a circle and I have no idea if the game is actually loading or not. Tried turning off PopUpOff. Tried turning off adblock. as it turns out it just isn't loading (firefox on win 11, if that matters)

what a beautiful city could be...

Loading information just goes forever. Console shows CORS violations and WebGL errors. Firefox on Windows. Recent ThinkPad provided by my employer.

Very amazing. And this is the worst it will ever be. We'll soon be exploring 4k versions of this and we can open every trash can in Tunis. Fascinating. Had a lot of fun (tedious tho) going out to Alcatraz and figuring out how to get in.

Ah nice demo! I flew around SF for way too long just enjoying the sights. On my M3 Air using Chrome it eventually just turns into blobs and my character get stuck, takes about twenty minutes. I popped open the DevTools and the game loads in at like 400mb but after five or so minutes I'm at 2GB of memory consumption. I'd guess that you need to have your agent do a couple of passes for memory leaks. Very fun otherwise!

The least amount of traffic I have seen in the city. /s

This is insanely awesome man; I turned the entire SF gov into an AI Gov. but this has really humbled me; great work dude.

Chrome on MacOS: largely unusable (over fiber); POV stuck and will not move except in a tiny area. I don't mind the lazy asset loading; I just can't go anywhere outside a couple blocks from the start position. M3 MBA.

Will try on my Mac. On my iPhone, I got the spinner wheel for a while and my phone started getting hot, so I killed it.

How do I turn the camera? Stuck with a single perspective.

zuzululu

where did you get the 3d map assets? also if one was serious about turning this into a game how would you go about it

DonHopkins

What's the actual game? Try not to step in doo-doo?

Nice, but the camera system is hard to grasp. I cannot turn the camera for the life of me. The camera is always facing north! Edit: I feel dumb now, I needed to click the trackpad to rotate, somehow I expected a two finger drag to move the camera :facepalm:

We got GTA SF before GTA VI.

Nobody defecating in public or play parties that are worse than going to the dentist 3/10

I lived in SF for nearly 20 years, though I mostly spend my time in New York now. And genuinely this made me emotional. Was weird as hell walking around my back yard. Going to the spot in Dolo that I used to haunt in my 20s. My favorite tennis courts and hill bombs, walked the entire disc golf course, etc.

I believe we're getting the hackernews hug of death.
