My first experience playing Quake was from a friend who had been to the US shortly after the release, and brought back the shareware version on floppies. I remember I quite enjoyed it.
Then I had obtained the leaked Beta3 (for the love it, cannot remember where from), and decided immediately to warp to the last level.

Little did I know that the last level in the beta was incomplete and could not be finished. 😀
Edit: you can now get Beta3 from here:
