Indie developer thatgamecompany has been known for small, arthouse games and such, but their last game, Journey, was a critical and commercial success and made them one to watch. And with the completion of that game, their three-game publishing deal came to an end with Sony Computer Entertainment, yet the developer has been radio silent on their next project ever since.
However, ex-employee Asher Vollmer wrote earlier on his blog about how he decided to leave thatgamecompany to become an independent game developer himself, and while he couldn't speak about thatgamecompany's next project (or as he called it: "The Game"), he did mention that part of the reason he left was because the development was moving slowly, even to the point of years left on the project.
It's unknown exactly how long the development will still take, but from his wording it'll be at least 2 years, if not more. Journey took 3 years to develop in the end, so depending on thatgamecompany's ambition, this new game could easily surpass that amount of development time. Despite the slow-going nature of the project, Vollmer had nothing but praise for the game, saying that it would change the industry.
Needless to say, it'll be interesting to see what the game is about when thatgamecompany spills the beans on it. Notably, Vollmer isn't the only employee to have left thatgamecompany recently; Matt Nava, the art director on Journey, also revealed back in early March that he had departed from the developer in order to found his own development studio, called Giant Squid Studios.
In the meantime, don't expect to hear much about thatgamecompany's new project. If Vollmer is correct, it could be years more before it's ready for release, but you can count on one thing for certain: the whole industry will be watching and waiting to see what happens next from the famed indie developer.
