Dead Space
Just finished on Hard mode. It's my second DS game. The first one is
Dead Space: Extraction (prequel).
Gameplay is smooth, some rare minor glitches with ragdoll effects and collision but it's not critical. Graphics is reaaaaally good for a 2008 game, shame it doesn't have anisotropic filtering in the options. Looooooooots of scientific inaccuracies/inconsistencies made me smile. Sound in vacuum, not all objects floated freely in microgravity, hydrazine flamethrower didn't work in vacuum and entire concept of planet cracking. And how in the Universe did flesh flies get to an abandoned space station in the middle of the outer space? Loooooooooool.
Playability is really good. With scarce ammo and healing items DS makes player think hard and plan each step. Ammo conservation was more crucial in Resident Evil but here it's well done too, thumbs up! Level design is awesome, devs managed to capture the atmosphere of the interstellar ship.
Weapons are pretty awesome. I used Line Gun and Plasma Cutter all the time. Didn't want to waste credits on other weapons when these two did the job. I don't like aiming in this game, it's pain in the butt really. In DS: Extraction aiming was extremely precise, you could literally shoot monsters in the eyes. Here you can hardly shoot some fat ugly monster in the belly! And what's with Isaac's stance? Like he's got some sever neck pain lol.
DS suffers from predictability and linearity, whenever you see a vent shaft you're 100% sure that necromorph will jump out of there and all doors will lock until you kill 'em all. You do it over and over again, it's a chore.
Puzzles are simple but some of them are really good, like the one with gravitationally tethered asteroid. It's pretty original, I've never seen anything like that in any other video game. Once again thumbs up!
Monsters are scary but not too much. They are monotonous and you fight the same darn monsters entire game. It looks like monster designers were really lazy that day. It also looks like they borrowed lots of stuff from Quake, Doom, Resident Evil, Stalker and The Thing.
Little bit disappointing because it wasn't scary at all and it was too linear. But it's ok, it's the first game in the series. DS: Extraction was really badass with better physics, harder bosses and smarter enemy AI. Shame, Eurocom don't exist anymore. They were awesome devs. In DS: Extraction they fixed everything that was wrong with original DS.
Weighing all positive and negative points I conclude that DS (2008) is a good game.
If DS: Extraction is 5/5 then this one is 4/5. I'm gonna replay DS: Extraction on Impossible mode and after that I'll replay DS on Impossible now wearing Military Suit.
.... and yeah Nicole is dead and Warren lies
I really loved Dead Space, and I've played it a lot! 
I didn't know about 60 FPS unlocking and I usually leave Vsync off. Aiming was a problem because I played original after the prequel, but it was fun to revisit prequel areas in the original game. DS: Extraction is well calibrated and has the most accurate aiming system I've ever seen. Even on impossible difficulty you can easily cut off toughest enemies' limbs in seconds because aiming is perfect. You aim for the joint and bam .. another necromorph lost its limbs 
(I was going for a deathless run but that did me in)
