Have you ever wanted to play a classic 90s video game inside a tweet? Neither have I. But now, thanks to the Internet Archive, you can embed over 2,400 free MS-DOS games directly into tweets. Is it useful? I’m not sure. Is it awesome. Yup!
Update (05.04.2015): Twitter killed the embedded games feature. And the fun.
You can also play those 2,400 MS-DOS games in your browser. But that’s so 90s.
