Good but frustratingly short. It wasn't super short in an absolute sense, but large sections were the TV show or cutscenes. They probably could have added in a score attack / scenario mode. Play as Paul Serene in a Monarch combat simulator or something. Maybe there's some levels where Martin is testing Paul's powers in the early days and sets up puzzle rooms as well. No cutscenes or story, just dump me in the room and let me play the game more. Whatever the rationale for it is, the gameplay was tight but there just needed to be more of it.
The game was a mess technically, extreme ghosting and on my PC version I had to run it in slightly-windowed-mode to avoid unplayably low framerates - the game would crawl to about 5fps on my 980ti if it was fullscreen 1080p. You set it to non-fullscreen, in an actual window (like you can see the start button and such at the bottom), and it runs relatively smooth. Ridiculous. There was also the loltacular issue (possibly caused by going above 30fps) of any object that characters were holding up to their heads would get stuck, and then teleport to catch up to the character. This happened with earpieces on Jack and Paul, you'd see the earpiece just hanging an inch or two behind their head then catch up to their head when they stopped moving. Also happened to Jack's (I think it was jack, was over a week ago and memory is fuzzy) cell phone when he was on the phone to someone early on.
Graphics other than the reconstruction ghosting and blurriness were very good. It's just a shame there isn't a no-comprimises version like I was hoping the PC would be, with full 1080p and no temporal techniques (irony? irony).
I agree with all of this, when I was really getting into the story it came to an end.
