A portion of a Skewed and Reviewed interview with an EA rep…
SR: Roughly How Long will the game take to play?
EA: The game should take about as long as it took players to play through Dead Space.
I have Dead Space, but I haven’t had a chance to play it. I don’t remember hearing complaints about the game’s length, though. How long can you really make an on-rails shooter? Oh, I’m sorry…a ‘Guided First Person Experience’.
