Who is your favorite character and why If you don't know what Undertale is, it is an RPG on steam that costs $10. The game has amazing character that you will grow to love (people who have played the game will know what I am talking about) and the best part about the game is that you have the option [i]not kill anyone[/i] or kill everything because you know, in this world [i]it's kill or be killed[/i]. But if you choose that route, [i]you're gonna have a bad time.[/i]
