So...

...Undertale ;)

(let the unnecessarily long explanation begin XD)

Long ago, two races ruled over earth: humans and monsters. One day, war broke out between the two races. After a long battle, the humans were victorious. They sealed the monsters underground with a magic spell. Now, legends say that those who climb Mount Ebott never return. A child climbs the mountain and falls down into a cave...this is Frisk (your character).

Frisk is determined to escape. If a monster absorbs seven human souls, it can break the barrier so all monsters can escape. Thus, though monsters are kind and gentle, as the seventh human, Frisk is in constant danger while underground. There are many times when she is safe, and she makes many monster friends...but when they see a human, most monsters' first reaction is to attack her. She has to earn their trust.

So in the game, you have battles like any other RPG, "a monster attacks you" :P But you can make it through this game by befriending every monster you come across. It's a very heartwarming and heartbreaking game, I'll give you that :)))

And that brings us to the endings. If you befriend every single monster and kill no one, you get a unique Pacifist ending and an extra two hours of content, ending with (spoiler alert) saving the main antagonist, and you and all your monster friends being freed on the surface. If you kill everyone to get a Genocide ending...let's just say the game makes you feel REALLY bad for every monster you kill, and on Genocide the game gets progressively creepier (the music gets distorted, there are new dialogues, etc). If you do a mixture of fighting and sparing, you get one of many Neutral endings. All of these end with you, you alone, escaping to the surface, leaving everyone behind. Then you get a sad phone call from the monsters, which is different depending on who is still alive...which just makes you feel worse for leaving them behind.

All this gets really deep, but I gotta admit...a lot of the game is a whole lotta THIS.

I mean...YES. XDDD

And then you have Papyrus. And don't get me started on Mettaton XDDD (You don't have to watch those though. But I recommend at least one XDDD)
