Gridless: New Horizons - An open world driving simulator with *somewhat* realistic physics and car models. The game drops you into an endless procedurally generated city with a full day/night cycle and live traffic lights. Drive freely, weave through traffic, and earn cash for close calls and reckless speed - then spend it in the Garage to unlock new cars.
A Tamagotchi style computer game inspired by the Disney Pixar's #95 Lightning McQueen
