I completed this game on the Xbox 360, and I\'m working on my second playthrough to pick up most of the remaining achievements.
It is really quite an amazing game. Yes, its like many action/horror games; go here, do this, kill everything in your path... but the overall quality and visual style is way beyond most other games. It\'s even superior to Fallout 3 in realism and believability. There\'s really no comedy in this story, with the exception of a few nutty movie posters on the walls in the crew\'s quarters. Dead Space is just dark, heavy and a little depressing. On my first playthrough, I got the distinct impression that all these characters were doomed, including Isaac Clarke, the main character. I won\'t reveal the ending of course.
By the way, I\'m sure most of you noticed that the protagonist\'s name is composed of two of the greatest Sci Fi authors of all time; Isaac Asimov and Arthur C. Clarke. No great secret I\'m sure.
If you haven\'t experienced it, you should give this game a try. I got it for $35 on Amazon.com. Well worth it.
