Steam kind-of *is* DRM. That said, I have so far been able to put in graphics mods and edit config files. I haven' tried a patched executable or adding the PTW executable and files from my CD Civ/PTW/Conquests yet. (Steam version does not include vanilla Civ3 or PTW.)
I would presume they did something to prevent you from copying the files to another computer and running without Steam, but I haven't tried that, either.
There was another digital purchase place that reportedly didn't have DRM. I thought it was GoG, but I can't find Civ3 on there right now.
GoG has never offered any of the Civ games (apart from Alpha Centauri) during the time that I've been a member. I bought a download-copy of Civ3Complete from Gamer's Gate earlier this year, for next to nothing (50% sale price was about Euro 2.50, IIRC) -- that's probably what you're thinking of, since it was you who started
this thread, where Quintillus (and I) posted about it...
Beyond the one-time authorisation key that you need to finish installing the zipfile, the GG version doesn't seem to have DRM -- obviously it doesn't need the CD, and (like GoG but unlike Steam) the game doesn't try to connect back to GG
each time you start it, either. IIRC, the GG-EULA says you can (re)install/(re)download as many times as you need to.
Downside is, the installation wasn't actually quite 'complete' either (although more so than the Steam version). The Vanilla1.29 .exe
was included along with all the Conquests stuff, however there was no PTW1.27 .exe -- even though the installation-process created a PTW directory (including the PTW goodies such as the Dinosaur units)! Though from an end-user PoV, this really only means that I can't play the CFC PTW-only GOTMs, I would have liked to be able to show my boys the PtW 'Dino-barb' scenario/mod I'd heard about (what small boy doesn't like dinosaurs?!), rather than having to build one myself...
