Branded by its own developers as "a small, broken, and stupid game," Goat Simulator is great for an afternoon of laughs. Originally a small demo built for a game developer jam session, the Internet at large clamored for more until Goat Simulator was released as an actual game.
Inhabit the true life of a regular, everyday goat as you break windows, get hit by cars, jump on trampolines, beat up protestors, get abducted by aliens, and more—so, so much more. Plus, the developers added multiplayer to the game post-release. Imagine how much ridiculous havoc you can wreak with two goats.
