SimCity creative director Ocean Quigley, along with lead architect Andrew Willmott and lead gameplay engineer Dan Moskowitz, has left Maxis to form a new independent studio called Jellygrade.
"We were lead developers on SimCity, SimCity 4, Spore and The Sims2. We love making simulations," Tweeted Quigley. "We're making a simulation about the dawn of life on earth; about lava, water, rock and the emergence of the first primordial creatures."
"We're starting off on the iPad with a fundamentally new simulation engine - I can't wait to start showing it off," he added. "We're building the new simulation engine now."
Most recently the trio worked on SimCity, which was released in March.
