Guacamelee! Super Turbo Championship Edition, despite the main game being a year old, proves to still be one of the premier downloadable titles around. Its expertly-tuned combat, responsive platforming and addicting exploration and upgrade elements make damn sure of that.
When Don't Starve is not rage-inducing, it's an absolute charmer. Its wonderful, Tim Burton-esque art style lends tons of adorable quirkiness to the proceedings as does the pleasantly gothic soundtrack. It's not a game for everyone, but those who revel in micromanagement and hoarding tons of supplies to take on the dangerous wild with will eat this one up.
