Well neither did I.
Consider me spoiled as I haven't finished Pacifist yet, but I'm close.
I probably never will do Genocide because, from what I've seen, is pretty sad compared to Pacifist.
I just really don't have a lot of time to play it because I keep dying on Asgore's fight with NO HEALING ITEMS and I'm too lazy to get gold to buy healing items from MTT-Brand Burger Emporium (because that's the closest shop)
