Trials Frontier

Eat my dust

Zillions of missions, tracks, achievements, upgrades, and a totally senseless unfolding storyline to boot: Trials Frontier is super simple in concept and unexpectedly deep in scope, keeping you playing just to see what weirdo twist will present itself next. The visuals are way above average both inside the levels and out, when you're interacting with characters or upgrading your hog. Leaderboards keep things competitive, although it's plenty of fun to play totally on your own as well.

Gotta give a huge shout-out to the devs for the design of the game upon first launch: no boring tutorial here; learning is fully integrated into the first experiences you'll have while playing. This is how it's done, folks.
