I played deadspace and it was very good. The story is great and so is the gameplay. (By the way watch deadspace anime BEFORE you play the game. It's available online for free if you know where to look. The anime really helps get into the story.
My only problem with deadspace was that it's just too damn scary and downright horrific. I really struggled with myself pressing on and on, but by the time I beat about 25 percent of this game it finally got to me. I just couldn't take it anymore, because every time I would play the game I would constantly turn around in my chair and check if anyone or anything was sneaking up on me... I got all paranoid.. So I stopped.
But I am planning to reinstall Deadspace at soem point and beat it to the end. I am not happy about the idea of Deadspace 2 because I haven't even beaten the 1st one. HEY GUYS, WAIT FOR ME!!!
I wouldn't say that the controls in the PC version are bad. Who cares if the input is ran through analog controller?! It WORKS! The controls DO feel stiff at 1st but you get used to it very fast, and the reason for such stiff controls is for the most part because it was intended this way to immerse you in the game and make you feel how heavy the suit that the main character is wearing is - not because the controls are broken or anything like that.
Also, the PC version is ages beyond the Xbox version when it comes to graphics. I own an Xbox360 and a PC but whenever a game is available on both platforms I always play it on a PC, because the Xbox360 is more for the exclusives such as Soul Calibur, SSFIV, Forza 3, Bayonetta etc.... You simply cant get those on a PC.
