As is tradition

No you have to edit the file for CD metadata and convert it to flac so you can pretend it was ripped from a CD, as is P2P file sharing tradition. Bonus pts if you put it through some filter to introduce a bunch of noise into the audio. Then ask in chat how you can convert a 128kbps mp3 to flac to increase the quality. Priceless.

It was pretty easy to find lists of half-life CD keys to play team fortress and counter strike for free.

Quake world & the quake fortress addon were fun and predates any CD key system so they could be easily found for free too.
