Toby Fox's subversion of Japanese RPGs is equal parts inventive, touching, and brilliant.

As a reviewer, the most difficult part about communicating Undertale's greatness is the fact that it works best when you're not aware of the many surprises packed within. 
On the surface, Undertale appears to be a loving sendup of the Japanese RPG genre, with many cues taken from Nintendo's EarthBound series of RPGs—specifically, Mother 3, a 2006 Game Boy Advance release that never reached our shores and developed a cult following as a result.

Regardless of its indie status, Undertale is one of the best and most inspired RPGs in years. By playing with traditional, turn-based mechanics, creator Toby Fox has crafted an experience with a legitimate surprise around every corner. If you have a PC and ten bucks, you owe it to yourself to play this amazing game.
