The first half of the game (Up till the amusment park) is great. The story is deep, narative, has good characters, and suprisingly enough, good music. The first half of the game (a common place tradgedy) is a great time, IF you can get behind the basic game mehcanics. (Don't expect total control of you character. you will use a "different" battle system. Its mentioned in the main reveiw, the "simon sez" thing). And as it progresses, you can really get pulled in to it. By the way, if it isn't clear, your buying/renting this game for the story, so my advice, wait till you can get this a bargin bin prices.
But then it will happen. About the last third of the game, you will go to the "amusment park scene". All of the story is effectivly ripped apart and the good, creepy story is thrown away in favor of some sort of super hero sub plot all put together in a hurry. Almost as if two different companys put it together.
If you havent bought it, wait till its cheap, or rent it. If you have bought it, but havent gone to the ammusment park, just stop when you get there and make up your OWN ending, trust me, you aren't missing anything, just an hour long sequence of "Matrix" rippoff fighting (With a nasty bug that will cause you to loose almost 90% of the time), a strange A.I cyborg (Up till that point not mentioned, hell, he just jumps in randomly under the disguise of another character whom before that point showed no cyborg/A.I qualitys at all.) something about a "Relic"...ya know what...the ending doesn't answer half of the questions it asks, like "What the f**k is the relic? and "How did a magical cyborg bring a dead character back to life?"
So yeah, to make the perfect metaphor: Its like a cook who was making a perfect meal, then went crazy and threw in every little thing he could get his hands on into the pot. Do yourself a favor, wait for the bargin bin. Trust me, this is one Prophecy you don't need to hear for $40.
