3. TimeO

Originally designed as a Ghostbusters game, TimeO was an incredibly imaginative game absolutely teeming with potential; it was to take place in New York City, which has incredibly come alive, with buildings and famous monuments making up the game's boss battles. Granted, Zootfly's other work has included the horrendous Prison Break: The Conspiracy, but this is one game that it would have been hard for even the lamest developer to screw up. Still, we're never going to see whether it would have lived up to all the promise, because the publisher went bankrupt in 2008, and though Zootfly posted a new trailer in 2011, they've still failed to find a publisher for it.
