I think you should go back to your XBOX games as you're memory is a bit off.
That said, the PS3 version is the worst of the three, but it doesn't really LOOK all that different. It's slightly jaggier than the 360 version and the framerate isn't quite as smooth, but overall, it looks pretty much the same. It's not a bad port.
I'm still going for the PC version, but the console versions are not that far off (main differences being image quality and framerate).
Are you serious?
What about the original looks superior to you? The first game relied very heavily on ultra simplistic, boxy geometry and ridiculously repetitive environment designs. FEAR 2 presents more geometrically dense worlds, more texture variety, vastly superior post processing (player weapon and camera motion blur), superior animation, and an all around more polished presentation.
FEAR was a very stiff, plain looking game. Despite its later release date, I always thought games like Half-Life 2 and Doom 3 looked much better overall.
The average FEAR scenes basically looked like this...
Even things like the player modeling are crap. Look at the players arm, for instance. That ugly thing is on screen throughout the game. The weapon models aren't very good either and everything floats around in a very unnatural way.
