Re: Who will buy Half Life 2 on Steam or DVD?
Yes, Steam files are stored as .gfd files in the SteamApps/*youremail* directory. If you burn them to a CD/DVD-R, then you can just copy them back to that directory and it won't need to download them again. Be warned though, some of those files will be huge, and HL2's full cache files will probably take up 3-4 CD-Rs. Also, I think that you can redownload any game from Steam once you've registered it (though that will obviously take a lot longer than copying them from a CD).
