The Internet Archive at archive.org, which has given us great things like the Wayback Machine, has launched the Internet Arcade, a web-based library of arcade games from the 70s, 80s and 90s. You can play these for free right from your browser. There's like 900 of them beginning with The Three Stooges in Brides is Brides.
We're talking Pac-Man, Tiger-Heli, Street Fighter 2, Q*Bert, Ghouls & Ghosts, Pitfall II, Paperboy, OutRun, Monster Bash, Millipede, Return of the Jedi, Indiana Jones and the Temple of Doom, Galaga, Frogger, Bionic Commando, and many, many more.
A message on the site says:
The game collection ranges from early "bronze-age" videogames, with black and white screens and simple sounds, through to large-scale games containing digitized voices, images and music. Most ga mes are playable in some form, although some are useful more for verification of behavior or programming due to the intensity and requirements of their systems.
Many games have a "boot-up" sequence when first turned on, where the systems run through a check and analysis, making sure all systems are go. In some cases, odd controllers make proper playing of the systems on a keyboard or joypad a pale imitation of the original experience.
Now set aside some time in your schedule to kill hours and hours of your life trying to relive your past. Seriously, you should probably set aside a few hours for Paperboy alone.
