6. RIP Opposition (GTA: San Andreas)

So many games have tried to emulate the Grand Theft Auto formula. There's been Driv3r, True Crime, Scar Face, The World Is Yours and, perhaps the guiltiest of all among them, Saints Row, just to name but a few. Rockstar have poked fun at the competition a few times now. San Andreas features a billboard that reads: "Get Rid of Old Rubbish Fast! along with "True Crime, Street Cleaners" written in the red and black font of the aforementioned GTA clone. Also, in San Fierro, there is a tombstone that reads: "RIP Competition, 1997-2004." Ouch.
