FEAR 1 is still pretty playable and looks half decent, though I wouldn't mind especially if they did something about the office building part of the game. That part lasted far too long.
The original 1998 Quake 2 engine one didn't suck; the second one, the Source engine, episodic one, did. And if they're remaking the second one, maybe the idea is to fix that. Take the good ideas it had and build a much better game around it.
But I'm pretty sure they're remaking the first one.
