Tarnicus: To others commenting on Steam as being DRM, it only uses DRM if the developer or publisher include it by using their:
"CEG (Custom Executable Generation) is Valve's alternative to the pitfalls of DRM and part of Steamworks, the company's free suite of publishing and development tools. What this technology does is register each copy of a game unique to one user, who can then use the title between compatible PCs without any kind of limits or root kits."
There are many Steam games who installation folders can simply be copied to other computers and don't even require the client once downloaded. Fortunately for those who care, GOG offers this with EVERY game :)
A lot has changed with Steam over the years and it is a hell of a lot better than it once was. I consider it a place to rent games mostly, not own them as I do with games from here and other DRM free sites.
Oh fuck it I got lured in to beating off that dead horse and feel dirty already :P
Sorry for bringing you back into this, man. You are technically correct right, however every list I've seen has been quite incomplete. Although that is the technical case, effectively it still remains DRM in every instance that I've been forced to use it for. But yeah, Steam itself is just the platform for the more notorious Steamworks DRM.
vulchor: A word of advice regarding Skyrim mods, coming from someone with almost 20 years modding experience and has modded TES games since Morrowind first released, stay away from the Steamworks mods. Not because I hate Steam, but because it doesn't do any of the things necessary to give a crashless modding experience, like load-order. It also auto-updates your mods, which can can cause catastrophe if you have multiple mods installed. Stick to using the Nexus Mod Manager and mods from Skyrim Nexus (the Nexus was the original mod resource for TES since Morrowind). Mods are usually released there first, and you'll hardly ever find the really good high quality mods on Steamworks.
Cyberevil: thankfully, I already do this. AND run Boss and still sometimes have to figure out what hates what on my own. Plus Nexus has the adult mods that you won't find on Steam either... Although even they draw a line that one other site (name eludes me now, I'm a little sleepy) crosses.
I haven't added even one mod off steam, even when it's not available on Nexus (my one complaint with them is they seem VERY temperamental, and ban great modders and mods WAY too often.
Good to hear!! Nexus didn't use to draw ANY line for mods, just as long as it was marked adult. Then came child rape mods. That didn't last long.
