Piss Off the Mimes

Mimes are littered throughout Grand Theft Auto V. But these supposedly mute NPCs will break character if you get them angry enough. If you do decide to attack mimes (why wouldn't you?) their health is astonishingly high, so bring a weapon ... or five. (Photo: Rockstar)

Transform Into an Animal

Grand Theft Auto has expanded the use of drugs throughout the series. In GTA V, players can find and consume peyote plants. After an intricate cut scene, players instantly take control of a mammal. Get this: NPCs still interact with you as if you're a human. (Photo: Rockstar)

Search for Bigfoot

In Grand Theft Auto: San Andreas, rumors swirled that Bigfoot could be found in the forests. Players searching for the mythical creature are rewarded in GTA V with two missions involving the cryptid. (Photo: Rockstar)

Punch Sharks and Find Treasure

Since Grand Theft Auto III, Rockstar has emphasized the aquatic side of the open-world game. GTA V takes it to a new level with random shark fights and buried treasure. (Photo: Rockstar)

Take All The #Selfies

With the rising popularity of selfies in today's world, it's no shock that the fun feature was added to Grand Theft Auto. The GTA selfie phenomenon has spawned its own website, where fans can post their favorite selfies from the game. (Photo: Rockstar)

Wreak Havoc!

Who would've thought the first Grand Theft Auto, with its original title of "Race 'n' Chase," would spawn one of the best gaming franchises of all time? The inaugural GTA game let players cause catastrophic damage while stealing cars. The novelty of that first game earns it a place on this list. (Photo: Rockstar)

Get Sucked Into a Side Mission For No Reason

Grand Theft Auto 2 instituted a wide-ranging gameplay option that's been adopted by nearly every open-world game: side missions. Those missions may not directly impact the main story, but they do often give birth to some of the most ridiculous characters in any series. (Photo: Rockstar)

Play Games Within Games

Staying in shape is a major factor in Grand Theft Auto: San Andreas, but Rockstar takes it to a whole new level in GTA V. If you're tired of running over pedestrians and high-tailing it from the cops, why not let loose on the golf course or find your inner chi doing yoga? (Photo: Rockstar)

Rid the City of Pigeons

Story mode and side missions can only entertain for so long. GTA IV mixed things up with an interesting achievement: kill 200 pigeons in Liberty City. Players could get all kinds of creative when it came to the disposal of the rats of the sky. (Photo: Rockstar)

Play Fetch ... With a Grenade

Chop from Grand Theft Auto V isn't the first pet to be introduced in the series. But this dog can be tricked into playing with a grenade. We won't tell you any spoilers about what happens next. (Photo: Rockstar)

Flip the Bird to the Police

Police are just so cumbersome in Grand Theft Auto. If you don't want to instigate a high-speed chase, Rockstar has incorporated another outlet for your digital road rage. While unarmed in a car, players can press the left trigger to give the one-finger salute. (Photo: Rockstar)

Fly Over Area 69

Area 69, the Grand Theft Auto version of Area 51, is an off-limits no-fly zone that first came to the screen in San Andreas. If you happen to fly over Area 69, you'll automatically receive a four-star wanted level. To survive such a harrowing adventure, steal a jet to defend yourself from the government (and aliens).

Skydive Onto a Yacht

Skydiving in Grand Theft Auto is a ton of fun. But try skydiving out of a plane onto a boat. Now that's fancy. (Photo: Rockstar)

Remake the Classics

When it comes to customizable, open-world games like Grand Theft Auto, players can take the creativity into their own hands. One fan of the franchise re-created the opening of Will Smith's old sitcom The Fresh Prince of Bel-Air with Grand Theft Auto's Franklin as The Fresh Prince of Rockford Hills. (Photo: YouTube)
