Stealthy
I don't know. These first few hours, it seems I've done a whole lot of running from A to B (i.e. following the glowy trail), pushing buttons and some occasional combat in between. Almost like an interactive movie thing. Maybe there will be more gameplay later on?
It does turn open world after some time, but even still the missions you can tackle inside that open world will still be quite linear in nature. When there are choices they're really highlighted, you click the option you want on the screen.
So there's not so much room to express yourself, and combat gameplay isn't so satisfying by itself that it would keep you going until the end, so if you aren't drawn into the story, care for the character and aren't immersed in the world, you probably won't enjoy the rest of the game that much either.
