Still don't understand this attitude. What makes a game replayable to people? Do people not rewatch movies or reread books either? You're going to replay it because it (theoretically) tells a compelling story with solid gunplay.
Non-linearity and freedom of choice, for starters.
I typically don't re-watch movies or re-read books because it's the same experience each and every time. The characters and situations never change.
With games, developers have the opportunity to deliver ever-changing experiences thanks to non-linear levels (with multiple routes and even hidden areas) as well as the freedom to approach things in almost any way you desire. Deus Ex is an obvious example of this, but there are many others as well. They don't necessarily have to be RPGs, either, as even oldschool shooters like Doom and Quake offered non-linear, highly replayable campaigns.
Based on everything I've seen and read, The Order: 1886 is little more than an interactive movie with some generic third-person shooter sequences strewn throughout. There is no exploration or discovery, and you're given little to no freedom in regards to how you tackle each situation. The story apparently doesn't branch off in different directions, either. The end result is a game with virtually no replay value, because after just one playthrough you've seen and done all that there is to see and do.
