No game is as good as a game that never actually came out. Prey 2 was going to be the ultimate open-world, bounty-hunting sandbox. Agent would have been Rockstar at its best. Silent Hills? Don't get me started on Silent Hills. The greatest horror game of all time. Probably. If it had actually, you know, happened.
Unreleased games are all potential and zero let-down, which probably explains why they continue to occupy so much space in all of our heads. Take, for example, Van Buren, the codename for a never-released version of Fallout 3 that was in development at the series' original studio, Black Isle. Even though many of its ideas later got recycled into Fallout: New Vegas, for plenty of stalwart fans it's still an object of intense fascination: An alluring what-could-have-been.
