Max Payne looks a little long in the tooth these days, but the game is still just as fun to play. Matrix-style bullet-time dodge your way through environments, killing enemies with style while looking like a complete and utter moron. This is a piece of history, and perfect if you jumped into PC gaming recently and missed out on some older titles.
If you're not willing to deal with the lackluster graphics, you can always pick up Rockstar's Max Payne 3, which is also discounted by 70 percent during the Summer Sale. Be warned, though: It's a much different (I'd say less "fun") type of game.
