10. All Vehicles Unlocked - The Simpsons: Hit & Run

Although there have been dozens of Simpsons games over the years, The Simpsons: Hit & Run may be the best of the bunch. 

The GTA III-inspired title perfectly encapsulates the spirit of Matt Groening's iconic show and accurately represents the town of Springfield. Thanks to the accessible controls, solid driving mechanics, and creative missions, someone unfamiliar with the 30+ season cartoon should still thoroughly enjoy it. There are plenty of activities to take part in, including winning races, purchasing costumes, and spotting well-hidden gags.

If players find and collect everything The Simpsons: Hit & Run has to offer, they'll be rewarded with... nothing. At least, that's what it seems like. But if a cheat code is punched in afterward, all the vehicles will be unlocked. 

Although every vehicle should've been purchased by this point, this cheat allows Homer and his family to drive cars, boats, and trucks that were inaccessible in certain levels. Also, each playable character can only drive certain vehicles in the main campaign. But with this code, this restriction no longer applies.

As such, there's nothing stopping the Simpson family rampaging through their hometown in the Mr. Plow truck, the Monorail car, or Knightboat (the Crime-Solving Boat).
