I can just feel the joy of Atari fans going apoplectic. A pioneer in arcades games, Atari has recently revamped its website and added a new section with with a handful of their classic games for you to play (for free) in your web browser. And yes, they have included the beloved Asteroids and Lunar Lander. Along with each faithful recreation, a online leaderboard allows you to submit your scores.
The fun begins at Atari Arcade.
Bonus: Another old favourite, Quake is also playable in your web browser.
