Contrary to IGN Screen Critics feels that Undertale is overrated:

Why I Feel Undertale is Overrated

Undertale is an adventure RPG styled game for the PC that has been extremely popular and loved for quite some time now. However, I have always questioned what makes this game so great compared to the other RPG titles out there. There are some issues I have personally found with the game that leads me to believe it is overrated for what it is.

My first issue with the game is the fact that it is considered an RPG despite the way the gameplay is. There are two routes a player can take within the Undertale: the Genocide route and the Pacifist route. Genocide is when the player kills every monster they encounter, and Pacifist is when the player spares every monster they come across. However, if the player takes the typical RPG Genocide route, there are consequences. I have a problem with this because a typical RPG would be for a player to defeat every single monster they encounter. However, Undertale punishes you for playing this game as a true RPG. Why consider this a true RPG if the player is punished for playing the game through as a typical RPG would be played?
