Extremely short, to the point where you might as well not play it at all. 8 minutes, maybe? When the credits rolled around, I was expecting to only have played the intro.
Deceivingly high production value, voice acting,and design, only for it to flounder out so quickly.
The only positive I can state is that pulling the camera control away to focus on an object while walking is a much better gameplay element than using a cutscene.
From a narrative perspective (because that's likely what the producers will use to justify the lack of content) Luggage is vague and cowardly. We don't know why Steve iced Gale. We don't much care, to be honest. The girlfriend line gets thrown away. The foreboding implication of luggage just turns out to be a metaphor emotional baggage, which I physically cannot about, because none of Steve and Gale's relationship or conflict has been built at all.
I'm really hoping somebody tells me it's one of those fakeout endings and you're meant to start the game again to continue the story.
