I have this old game from 1999 that I still play from time to time.

 It  was originally released as a Windows game, but some guys ported it
 to Linux. It's a 32 bit binary and  comes  with  some  bundled  shared
 libraries (also 32 bit), but that thing still works. That's amazing. I
 use PulseAudio these days and a 64 bit OS and I have  an  Intel  iGPU,
 but  it  still  works. Dude, that thing was probably written for Linux
 2.0 -- still works.

 I wonder when it'll stop working.
