Need Some Video Game Help, Guys

Everyone keeps suggesting Dead Space, so I might want to try that one out. On a scale of 1-10 though, with 1 being shit tier and 10 being crap-your-pants-and-don't-sleep-for-a-week, how would you rate Dead Space's horror intensity?

About a 5-6 for me.
I played in the dark at two in the morning.
