Odd to call it the "ultimate Remedy game" since we've only got two real points of reference for that, AW and it's sequel, and while both were good, I wouldn't say they set the bar particularly high.
It's good to hear that gameplay in Quantum Break is "at it's heart" though, because what I liked about AW was the interesting, more experimental combat for the genre.
AW doesn't have sequel xD
Maybe you were referring to Max Payne?
Well by sequel I meant American Nightmare
Mmmm...true. Though that's more like an experiment than a full-fleshed sequel.
