That really isn't what you said, more or less. You said it was fake and there was no information online about it. I was merely informing the members here that this game is real and there is a good chance that it will be released.
The IP problem more than likely has to do with licensing and the Ghostbusters movie plot, quotes, and characters, which the ZootFly CEO says that "There's actually no insurmountable problem with getting the IP. It's just that extra mile someone needs to stride to get it."
He also mentions that the engine is based off of their other game currently in development, called TimeO, and is only a prototype. This could be changed or modified. The videos were released mainly to raise public awareness and start some hype to show that pursuing it wouldn't be a waste of time.
I'm not trying to start an argument war, just trying to get the facts straight.
