Someone should build a shrine to Jason Scott and the rest of the team at the Internet Archive. These folks, bless their collective cotton socks, have put 900 old, coin-operated arcade games up on the website, all for your especial vintage gaming pleasure. The site, dedicated to the preservation of computer history, also has a classic console gaming emulator, among other treasures.
It takes a bit of patience to figure out the ins and outs of the site, and not all the games adapt well to keyboard gaming, but these are minor quibbles compared to the hours of nostalgic fun you’re in for. Stop wasting time on the internet and… er, go spend some time on the internet, then.
