I'm a pretty good fan of the FEAR games. I've got all of them for 360, including the DLC campaign for FEAR 2 and the FEAR Files expansion.
To be honest, the story line can be better. The FEAR gameplay needs some improvement, which they fixed in FEAR 2.
FEAR 2 really kicked it up a notch. It was a great game, and even the DLC campaign was good.
The only problem was that it was too short, and the endings left you hanging and wondering what the

was going on. The endings were the downfall to the games, in my opinion.
Overall they're definitely games you need a "feel" for in order to enjoy them.
