4. Payday 2
Payday 2 is actually a REALLY recent game, and you probably have at least heard of it. The sequel to Payday: The Heist, Payday 2 puts the player back in the shoes of one of four gunmen in a criminal crew whose mission is quite simple: steal as much damn money as possible. Players have the choice of four class builds, a hundred or so weapons, and an astounding number of weapon mods. From there, you hop online and get thrown into mix of amazing mission including everything from jewelry store smash and grabs to sneaky art gallery cat burglaries. What Makes it a Classic? Replayability. Plain and simple, this game could be played a thousand times and be different in each encounter. Borrowing theoretically from Left 4 Dead, Payday 2 uses a director program to randomly modify maps by changing the location of cameras, lock status of doors, number of guards, presence of metal detectors, and a dozen other things. Each time you drop into a mission, even if you've done the same mission a dozen times before, something unexpected might happen. Sometimes that unexpected thing makes the mission go flawlessly. Sometimes it causes a catastrophic failure. Additionally, the game is just chalk full of stuff to do. The number of missions is actually quite impressive. Players can burn down meth labs, hit convenience stores, crack bank vaults, sneak into senators' houses, even infiltrate the FBI. And each mission is fundamentally different, requiring a different approach for success. That, combined with the immense amount of unlockables to go after makes this game one that stands out well above the crowd, despite having seen only limited financial success.
