Each year, I wait for something to come out to blow me away. FEAR was the last one that I actually could not get enough of. Now PREY appears, and WHOA, what a ride. Fantastic visuals (I mean FANTASTIC). Great dynamics in control of the characters, cool weapons, the anti gravity stuff and portals are mentioned quite a bit by most who comment on this game, but they are just part of the whole thing.
The voice acting is almost uniformly great (with the exception of Jen sometimes), and the story is mostly original, save the overall plot, which we've seen a zillion times before. But the characters are new to the genre, (nope, no super human marines, or master gunfighters) and treats the traditions of the cherokee with respect and dignity.
There are some moments where it feels like some other games, an occasional dopey boss battle, and too many elevators, but wow, the overall pace, artwork, character control, and AWESOME MUSIC makes it the most movie like video game I've EVER played. Yes, even more than Half Life 2. The health regeneration is a little annoying at first, but then you learn to appreciate it somewhat, as it is less disruptive than having to go back 2 or 3 saves and start over.
One more comment on the music. I was amazed at how cinematic it was. I felt like I was in a live action movie sometimes. Just awesome.
My library of PC games numbers over 100, and I've played them all. But this one is in a class by itself. Yes, its somewhat short, but the work that went into it was intense.
I would ignore most of the adolescents that talk about the "doom 3 engine" (heck most don't even know what it means, they are just repeating some noise they saw on some forum somewhere). What the inside technology is has no bearing on the implementation of the game, story, visuals, music and scenarios. This thing is just plain great if you like the alien/hero shooters.
I can't wait for more. Kudos to the developers and artists that built this thing. What a piece of work
