For the most complete experience - make sure you watch animated movie "Dead Space: Downfall" before you play. And then just immerse yourself into the story and forget about sleeping lot next few nights. As long as you are into survival horror 3rd person perspective game with great atmosphere and jump scares, you are going to love it, and long winter evenings are going to dissapear extremely quickly. One of the best games in the genre. Pure unforgettable classic. PC gamers have to be aware though. There are parts of the game (mainly boss fights) more familiar with console world and although they might get frustrating a bit, they don't ruin the overall experience that much. One has to remember it is a port after all, and as such, doesn't fit 100% what PC gamers are familiar with. Some also had complained in the past about controls, but I had no issues with those and while not perfect, one can get used to them pretty quickly. Little caveat - I don't own GOG version, I used to play with fully patched DVD version of the game, so I imagine, some issues might have gotten fixed.
