Aside from the gorgeous graphics there are many things about this game that I didn't expect. While I won't go into the story as I rather not spoil it the way scenes are "shot" look fantastic and feel like a film at times. Though it's a different theme, I got Tarkovsky's "Stalker" vibes from this but I'm not sure I can really explain as to why other than the heavy dialogue throughout. It touched on religion in a way that wasn't edgy and I felt posed some good questions in morality among other things.
While it is short and a walking sim I think this game does a great job in telling a story that kept me interested in it even if it wasn't always action packed.
