Meme game made by indie developer Toby Fox. Undertale became such a big hit that Toby's now swimming in cash and laughing at the retards who spent millions in making a game that sold less than his.

You should play Undertale

A fucking awesome game based off, Earthbound. Realeased 9/15/15. This game has many secrets such as... W.D. Gaster (spr_mysteryman_1, spr_mysteryman_2, spr_mysteryman_3) and the lava guy room (i like to call them "Lava Guys"), Napstablook's house (dont know where its located), and the room that represents Toby Fox, the creater of the game.

"YOU HAVE TO EAT DINNER TIMMY!!"
"No mom, im playing Undertale! Sans is kicking my butt right now!"

undertale 

A game created by Toby Fox, where you star as a human in an underground society full of monsters. You can spare, or kill your enemies, which teaches people you don't have to murder everyone!

There are three routes.

Pacifist is where you spare everyone and no one dies at all, (Which is honestly the best ending.)
Genocide is where you murder everyone in the underground, which results in a lot more sobbing and feels if you play it after pacifist.
Neutral is where you killed a few and spared most, so like the middle man.

Girl: OMG! Have you heard of Undertale?! It's SUCH a good game!
Girl 2: Never heard of it,
Girl: BITCH! GET OVER HERE! *Tackles*

An RPG created by Toby 'Radiation' Fox and a few others. Became popular at the end of 2015 due to a Kickstarter a few years earlier and a lot of famous Youtubers (most notably Markiplier, Jackscepticeye and Steam Train) doing Let's Plays of the game.

"Have you played Undertale yet, dude? It's such a fun game."
"No, man, don't have the funds. I'll watch a Let's Play until I got enough money to buy it."
