By "route", we mean "path". Fact is, this is the world of Undertale. If you kill everyone, the events of the Genocide Route play out. The fact that the world is not a game will not change the consequences of your actions, other than making them real. Chara taking your SOUL has a MUCH bigger impact as a result of this. So, take what you plan on doing.. And convert that back into game terms to answer the question. If you would help the monsters, and free everyone, that's Pacifist. If you kill everyone, Genocide. And if you just reach the end without doing either of them, that's Neutral. There IS a fourth possibility, but you said you weren't doing that.

Canon does expand, but it is not altered. The world as a game is the same as the world as reality. Sure, you might have more options, like exploring the Waterfall castle, looking over through New Home, and you won't get locked out of the world mere minutes after reaching the Surface, but canon rules still apply. The only way to get an ending/action/scene not programmed within the original game is by doing something that wasn't programmed within the original game without breaking established rules. (Though you could read what the glyphs about the legendary artifact say! ..Still can't stop that dog from absorbing it though.)

Anyways, you were brought into the world of Undertale. First place you find yourself is the group of golden flowers at the start of the game. You don't lose your memories of your time on Earth, so you'll be quick to find out you're now in Undertale's world. At the LATEST, as soon as Flowey shows up. Probably as soon as you spot the Delta Rune on the door prior to Flowey.. If you DO spot it, that is. You know something, or someone, brought you here.. But not what, who, or why. Maybe Suzy has something to do with it, though.. Synchronicity...

Anyways, Grant just described exactly what it would be like if you couldn't S/L/R perfectly. That's exactly how a SAVEless run would work. And the reason why the fourth option would be a somewhat popular choice.
