Just finished Condemned 2 on PS3. Very rough execution. It had neat concepts, but it was like the lead designer was telling them what to do over the phone. No one ever said "Yeah, have a UV light to look for blood smears, but ALSO, don't have enemies running into railings and unable to get upstairs..."
I liked that it didn't hold your hand through some of the investigation sequences, and asks you to recall things that happened, and make guesses based on the evidence you have. That was all pretty cool.
