Every now and then, though, a promising game will go through development hell and end up being canceled, disappointing those who were eagerly awaiting that game's release. Not all of the entries on this list have been officially canned, but their status at least remains in limbo. Not all hope is lost on these titles, though. Duke Nukem Forever has showed us that keeping hope alive can still pay off.
