Offbeat developer Thatgamecompany revealed its third game designed to challenge "traditional gaming conventions" on the PlayStation 3, as the studio did with previous releases Fl0w and Flower: Journey, an online game with a unique and beautiful visual style.

The Los Angeles-based studio explains Journey's premise:

"An exotic adventure with a more serious tone, Journey presents TGC’s unique vision of an online adventure experience. Awakening in an unknown world, the player walks, glides, and flies through a vast and awe-inspiring landscape, while discovering the history of an ancient, mysterious civilization along the way.

Journey’s innovative approach to online play encourages players to explore this environment with strangers who cross their path from time to time. By traveling together, they can re-shape the experience – creating authentic moments they will remember and discuss with others."

Thatgamecompany and its creative director Jenova Chen plan to formally present the game at E3 in the next couple of days, so expect to hear more about it soon! Journey is currently slated to release some time in 2011.
