I really liked fear, but am not a fan of hl2. I also liked the first expansion for fear but thought the second was crap. It's pretty funny that we seem to like the exact opposite in games.
As to re5, I played it through split screen on a ps3. The frame rates were horrible, the resolution was so low that I couldn't see the trip mine wires, the QuickTime events killed me over and over as I put the controller down during the cutscenes, the gameplay was not very good, the controller was horrible to aim with, and the story is silly. The game is pretty crap. All that said, any game that has coop is automatically 10 times better so I still had fun playing it. If I were to have played the game single player I doubt I would have gotten very far.
I really do like fear. I played it a ton, and still load it up once in a while. And every time I do I am amazed how it still looks better than a lot of fps games that come out now.
