Goat Simulator is an odd game. I think even calling it a game might mess with your idea of what you're getting yourself into. It has a score and some achievements, but first and foremost, Goat Simulator is a sandbox.
In Goat Simulator, you explore a map, just as you would in Gerry's Mod or if you were merely running around Liberty City in Grand Theft Auto. But there's a catch: You're a goat. You can jump, head-butt, or just fall over and faint. You can destroy the town, find crazy jumps, or just wander around.
You score points from carrying out crazy stunts and causing destruction, and you can earn more by enhancing your goat. You can give him a jet pack or let him shoot Spiderman webbing, or even change him into a penguin. You can unlock other changes as you play.
To enjoy this game, you need to have no expectation of a storyline, and you need to have fun just messing around with the environment. I was pretty skeptical until I found the giant slingshot. I then started searching around for other weird things to entertain myself, and the game just clicked into place.
What's Good: Fun sandbox with lots of options to mess around with.
What Sucks: The non-traditional nature of the game may turn off some players.
