The route selection is the opposite of random. Your first two choices determine which of the four routes you get.
Wait...there are routes? Going off of that, I think I might be playing through Maccon's
Random as in I, as a player, could not choose the route that I want. The choices are unlabeled and therefore, I can only choose randomly and hope for what I wanted.
It takes very little experimentation to figure it out, so it hardly matters. Anyway, enjoy.
