I haven't played the game - I put it on my Gamefly list, but I'm already a little bummed out about it.
I caught the mini-documentary over at Gametrailers, and it looks like the original title had some really cool features. It was going to tell the story of a father who's young daughter had been lost because of changes he made while time traveling. Evidently, changes which also caused the world to shift to one based on steampunk technology. So he has to go set things right.
As a dad, I thought this was a pretty cool idea, and the steampunk element was certainly unique.
But - I guess Sierra wanted something "easier" they could put into a franchise. So now, you are a nameless, mute hero that you never see (kind of like Half-Life), living in a dystopian future (kind of like Half-Life 2) where you have cool time travel powers, but you don't know what the heck is up with the story or why things or happening until you get closer to the end (kind of like - well, you get it).
I saw the original bits they were going to do, and I'm disappointed. They had a cool, original idea with a story that had some emotional impact. Looking at the "new" look and story feel, I can't help but feel like they gave up something great, in exchange for something more ordinary.
Guess I'll find out in a couple of months - or whenever I get around to renting it.
