I'm just going to leave here an excerpt of the text I posted on my website about this game. It alone serves as my comment here:
"I can say, in my opinion, that Northbound: Long Road Ahead is one definitive proof that video games have long since ceased to be something considered "childish" or "silly", but that they have evolved to the point that they have become a tool to connect the player with remarkable, deep and reflective stories."
