OUR TAKE Not a game yet, but the best browser city anyone has shipped.
How to play
-
Open nyc.somethingbig.ai in a desktop browser and the Flatiron district streams in around you; this is an early preview, not a finished game.
-
WASD walks or drives, Space is the handbrake, F gets you in or out of a car, and V turns the car into a helicopter.
-
Left click fires, M toggles sound, and B opens the feedback box the author is using to decide what to build next.
Scoring tips
-
Press V early: flying is the fastest way to see how much of the city actually exists yet.
-
Grab a car and drive south on Fifth — the traffic and the pedestrians are the most convincing part of the demo.
-
B is the important key here; the author asks for what looks wrong, and the city is being built from those reports.
-
It streams as you move, so give the streets a few seconds after you land somewhere new.
