Actually, not only is he right, but this is likely to be one of those titles, because they're not likely to bother to implement Steamworks on something so old. That was my point in the post I made earlier -- old games on Steam generally don't have DRM added. It will throw up a DRM error if you try to use the shortcut Steam sets up while not logged in, but if you go to the actual .exe file in the game's folder, it doesn't even need Steam running to work, and you can even set up your own shortcut from that file, if you want. I've got quite a few games like that. Rule of thumb, if it's non-Valve and pre-2004, there's no Steamworks on it, and really most non-Valve stuff pre-2007 or 2008 is likely to work just fine. A fair few indie titles don't use it, either.
I actually find it really weird how when I joined this site, I was one of Steam's greatest detractors in a nest of Valve worshippers, and I now find myself pretty frequently defending it against people who have the wrong impression of how it works. I /hate/ DRM, and I hate that Steam is little more than a pretty implementation of it, but to hear some people talk you'd think it was Starforce or something.
