"Dust: An Elysian Tail" (yes, I spelled "Tail" correctly, and no I still don't know why) is a fun, quick, and pretty action RPG.
The protagonist is Dust, a hero with amnesia who must save the world from an evil army. So, the plot is nothing new. And while some games, like Bastion, have such a strong auditory and graphical narrative that greatness wolud shine through even with an unoriginal plot (not that Bastion is unoriginal), the narrative in "Dust" seems a bit hokey.
That said, I played "Dust" because I wanted something fun and mindless, and in those respects, it performs admirably. None of the challenges are too hard (even on a high difficulty setting). It has RPG-style advancement (better gear and experience levels), so you're always achieving some goal in developing your character. The combat is button mashingly fun. And, while the settings aren't breathtaking, the game's graphics are pretty.
