This is a fantastic game. I question the reasons behind some of the lower scores that it has achieved. I'm honestly much more pleased with this game than I am with Gears of War. I do believe Lost Planet is the better game.
What makes Lost Planet such a great game? There are very few games that while playing you forget your playing a game. Lost Planet totally accomplishes this most convincingly in several important areas.
The thing that most drives this game for me is the collision detection. Not many games boast a physics engine this robust and this well intergrated with the collision detection. Creatures that roll into you, run over you, and genrally mess up your day do so with pixel perfect collision detection. You will never feel cheated when you get hit by something. Its an amazing difference when your in a battle with many creatures and you are being realistically knocked around by all the enemies. This game creates the kind of tension you would experience while watching the movie 'Aliens' and its mostly due in my opinion to how solid the world feels due to physics and collision detection.
The next area where the game excells is certainly in gameplay. There are more gameplay mechanics going on as you play this game than are offered by many of its modern contemporaries, mechanics that all flow naturally out of a perfect control scheme. None of the mechanics ever feel forced or required, it always manages to maintain an air of authenticity in the pioleting of various mechs and firing of numerous weapons. Theres a lot to think about while your playing this game but none of it really hits you over the head, it all feels very natural and intuitive.
Suffice to say the graphics are excellent, especially for the amazing boss battles that occur at the end of every level. Thats right your treated to some downright huge and amazing bosses most of which have unique enough attacks and defenses to make fighting each one feel like an original experience. Even though completely different in scope I was reminded of Megaman style boss battles, on a much grander scale. I never found myself upset even when having to face one of the bosses (The green eye) at least 15 times before I passed him. It was all amazing fun the entire time.
I've had more fun with this game than the entire time I played Gears of War, not that I thought GoW was a bad game, just that after playing Lost Planet I definately think LP is the better game.
There is a negative; the story is boring and disjointed and adds little to the over all experience. Trust me however you'll be having so much fun playing the game that you won't even care about whats happening in the cut scenes, but its a shame they didnt try harder with the story.
