Pretty much Exactly What It Says on the Tin: Goat Simulator is a simulator game in which you play as a goat. Originally a silly experiment done internally by Coffee Stain Studios, but it unexpectedly gathered interest from gamers. Goat Simulator is a treasure trove of broken physics and silliness.Buy it here or on Steam here.
Tropes present include:
Alien Abduction: You can trigger one. You get stranded in space until you choose to respawn.
Ascended Glitch: Word of God says that the only bugs that will be fixed are the crash bugs. Everything else, particularly the variety that involves the physics engine doing weird things, will be kept in under the justification of Rule of Funny.
Awesomeness Meter: You can get points for stuff like making things explode, crashing parties, and doing 360 flips.
The physics in this game can result in some fairly disturbing-looking positions for anyone involved. Walk up any ladder and watch the goat's head twist in all sorts of unnatural ways. The Demon Goat power activates a black hole in front of your goat that can inflict this on other objects and people.
Combine two or more goats when at least one isn't just a cosmetic change. For example, Space Goat and Ripped Goat. The June 2014 update actually added this example as Slendergoat on the beach map.
Combos: Like a skateboarding game, you get points for doing flips and spins. Hilariously, the "combo counter" doesn't settle for boring double, triple, and quadruple. Using various tricks, it's possible to go right past real numbers and into Integer Overflow numbers, which when done enough can actually net the Hard level high score achievement in a single combo. In fact, if you go too far, it is possible to achieve a literal integer overflow and do a combo so insanely high that the score resets to 1.
Cool Mask: You can earn these by completing some of the objectives, such as going to the Goat Castle and proclaiming yourself King/Queen of All Goats by sitting on the throne.
The Dev Team Thinks of Everything: It's possible to destroy the hang glider by licking the Boulder of Death and dragging it to the top of the crane. Doing so will net the message "How? Seriously, how did you manage that?"
Die, Chair! Die!: There are very few things in this game you can't headbutt for points. Pretty much anything not nailed down is fair game.
Going Through the Motions: There is only one short animation loop for dancing. Finding a big crowd doing the same dance move over and over again, perfectly synched with one another to boot, is both hilarious and slightly unnerving.
Hitbox Dissonance: In line with the intentional brokenness of the rest of the game, the player character in Flappy Goat has an extremely unforgiving hitbox in which even if you come within two pixels from an obstacle, you'll still lose.
Hookers and Blow: On the beach map, it's possible to find a house with a pile of "sugar" neatly cut into a line. Licking it increases the game speed for 30 seconds or so.
Involuntary Dance: Deadgoa7's active power forces everyone in the area to dance, even when they're fleeing in terror.
Jet Pack: You can pick up a jet pack on the city map. You cannot, however, control your flight. There's also Rocket-Skate Goat. In this case, your legs just bounce around in every direction and it does absolutely nothing. You can even walk around.
Giant Goat. Understandably, a beached whale is a bit difficult to move around.
Shopping Goat. A shopping cart is easier to move around, and can even jump, but it's an inanimate object that can't headbutt.
Knockback: As part of the messed-up physics, a lot of things will cause your goat to go flying across the map.
Lightning Bruiser: Classy Goat (a penguin) is the slowest goat when walking, but has the fastest running speed in the game.
Mushroom Samba: The beach map has mushrooms you can eat by licking. Doing so causes the goat's head to enlarge. You have to put down a few of them to get the full effect, or else it will only enlarge an ear.
Not Quite Flight: Angel Goat reduces gravity to a fraction of normal as long as its power is active. You can leap off the tallest building in the game and land with the grace of a cat. This makes getting absurd combos hilariously easy, and is great for general travel.
Overly-Long Tongue: Licking something causes the goat's tongue to stuck to it... and stretch to freakishly long distances if that thing gets stuck somewhere.
Ragdoll Physics: Knocking over human characters will cause them to flop to the ground in a very strange way. Your goat will do this too — in fact you can get it to "ragdoll" on command by pressing a button, which is actually vital to getting one of the trophies and one of the achievements.
Rule of Funny: Why are the physics so messed up? Why can you lick things and then drag them around with your tongue? Why are there trampolines at the bottom of an empty swimming pool? This is why. The creators have outright admitted this: one of the key features on the Steam store page is "MILLIONS OF BUGS!", with the disclaimer that anything that doesn't crash the game is "hilarious and we're keeping it". You even get an achievement for crashing the game.
Scoring Points: The "goal" of the game is to complete objectives and earn points. Some of these objectives are given to you, most you have to find for yourself. Some of the basic ways to earn points are by destroying things, jumping over things, or licking things.
Near the dam on the beach map is a crashed spaceship. On the hotel balcony is a towel with the number "42" printed on it. Combine the latter with the former and you become Hitchhiker Goat, which has the power to summon whales from the sky.
The beach map has a hat store. You can steal money from around the map and trade it for hats.
Stuff Blowing Up: Some things explode when you run into them. Also how you get the Michael Bay achievement, by blowing up the gas station.
Stylistic Suck: Could easily be called Stylistic Suck: The Game. It's a mediocre premise in a game that's intentionally filled to the brim with glitches and terrible ragdoll physics. It's essentially if someone made a terrible G-mod video into a playable game.
Super Strength: Ripped Goat comes with a massive increase to headbutt power. The one you fight can headbutt you high into the air.
Unlockable Content: Collecting trophies and completing certain in-game events unlock new goat skins (some are applied immediately, others can be activated in a Custom Game). These include Tall Goat (giraffe), Feather Goat (ostrich), Giant Goat (whale), and many more.
Up to Eleven: It is possible to flip so many times that you achieve "Integer Overflow" combos.
Villain Protagonist: The goat can beat up innocent civilians, destroy stuff, and participate in a Satanic ritual, among other things.
Walking Disaster Area: Repulsive Goat's ability emits a stench which is literally repulsive; anything that gets near/touches the goat is instantly repelled, assuming it is an object the goat would be capable of moving. Intact and moving cars aren't affected, instead causing the goat to ragdoll and stretch from the interaction.
Wall Run: A new feature added with the June 2014 update. By running and then jumping at a wall, the goat will run up the wall for a brief period. If there's another nearby wall, you can jump to that wall and keep running. Angel Goat can scale a sheer wall through its hover ability.
