Papyrus is the only Undertale character I actually give a **** about.
Don't get me wrong, it's a great game with great characters, but honestly I don't care what happens to the others. Papyrus is the only character I was like "Wow, how could anyone kill this precious thing."
I just finished my first playthrough in one go today, true pacifist style.
Like.. my role in my group of friends is to be the asshole, and I don't think I culd bring myself to do a genocide run of Undertale, I just like all the characters way too much
On a somewhat related note, I actually ran into someone with the username 'The Great Papyrus' While playing prop hunt last night. He did a pretty good voice impression too (I assume anyways, I've never played Undertale and I'm pretty sure there's no voice acting, but he sounded like I would imagine the character should sound). I'm pretty sure there was a player named Sans as well.
Just kinda thought it was neat to meet someone who managed to grab the original character name first, and also played the part.
