I am curious as to how it is possible to start playing CS 1.6 after downloading so little from your Steam account.

The game is approximately 300 MB, and after something like 5% you can start playing. (The download even pauses while you're playing.)

How is that possible? Is that part of the game all there is to be able to play, what is all the rest?

    Er, I'm pretty sure this isn't true. Are you sure you're not just downloading an update (in which case, you won't be able to connect to most servers running the latest version)? Commented Mar 5, 2012 at 17:40
  • @BlueRaja-DannyPflughoeft No, I'm not a gamer, the only game I have is Portal, maybe that is it, but it's the only game I have. This verified on THE FIRST TIME I downloaded, I'm sure of that.

  • @StrixVaria No, only Portal, the first one.

Steam allows for games to specify the minimum content required for launching a game.

This feature is more often used for single-player games where you wouldn't realistically need more than the first few levels right away.

From your description, it sounds like CS does the same, being that the maps and map-specific models are the largest pieces of content and you can't play all maps at the same time.
