The newest game in the Adult Swim line-up is Burrito Bison Revenge, and I am freaking addicted. It's one of those launcher games where the goal is to travel the farthest distance possible, but developers Juicy Beast have refined the gameplay into something that's not only considerably deep, but actually has narrative as well.
As the Burrito Bison, your objective is to, well, I'm not too sure, but it involves traversing some sort of land inhabited by gummy bears to retrieve your wallet. Yeah, it's wacky, but the aesthetic works, and with numerous upgrades to grab, you'll be playing this one for a long damned time. I started up the game again just to grab a screenshot, and I ended up playing for two hours. Oops.
