TimeShift/Trivia

Executive Meddling: The game started out development under Atari and was based more on the idea of using your time traveling powers to solve puzzles, but in early 2006 a demo was released to the internet, and its reception was... bad, to say the least. Atari apparently panicked and sold the game's rights to Sierra, who in turn told the development team to trash virtually everything they had done and remake it along the lines of the then-recent megahit Gears of War.
Hey, It's That Voice!: The rebel leader is voiced by Greg Grunberg, best known as Matt Parkman from Heroes.
What Could Have Been: At one point the game was going to feature a steampunk setting and much weirder and more interesting weapons, but Sierra basically/literally (according to a profanity-laced interview) said "the fuck is this" and hammered it out into a different type of game.
- It was more the released demo of this version being horrible that led to Sierra completely retooling the game into a Gears of War esque game, rather than simply the style of the game itself.
