This is not Sim Related but its good for the "Lets Plays" on YouTube. Dead Space is free at the Origin Store and TheRadBrad has a great vlog of his play in the game if you get stuck, He is using the Machinima portal and though he is very good he does show the way to get past the puzzle traps without giving too much up. He also has the radio personality down for it so its not too annoying. He doesn't do the trophy collecting type stuff that a lot do.
Some people have a Guardian Angel, you know a little guy sitting on your shoulder that tells you right from wrong, but mine is an Idiot.
