But it isn't. In several cases, it merely acts as a downloader and you can copy the game folder to another machine and play as you wish.

Downloading as a means to DRM the product though, forcing a download install even for a retail release.

besides, personally I want download & installation as separate events (as they are with GOG) not at the same time.

Nonono, you're making your life worse by opting to not buy products with whatever you consider DRM. Principles are nice and all, but it's you who set them - don't whine if you chose to do so.

Buying products with DRM = different standpoint on the matter. You are very much calling people jerks for disagreeing with you.

Actually all Steam does is to download the game. There's no proper installation process, just prerequisites.

Actually, any installation* done with Steam is done at the first launch of the game**, not on download. What you could call "installation" on download, is no different from extracting a zip archive to a single folder.

* such as: registering DLL's, shoving files into system folders, setting up registry keys, or whatnot.
** For DRM-free titles copied to another machine, this can just as well be done by running the bundled prerequisites (installers for .NET Framework, DirectX, etc. Steam just runs those automagically when launching the game from within Steam).
For Steam'd retail releases. Agreed.

Not this again.Sheesh

It's still not disagreeing. There's no opinion involved. It's perfectly objective. Stop for a moment to try to think abstractly.

1. It's unquestionable that DRM harms consumer rights.
2. Buying a DRMed product reinforces DRM as an acceptable thing for a publisher to do.
3. (Encouraging more DRM use.)
4. Thus, buying a DRMed product is an act of harming consumer rights for everyone, everywhere.

It's just like one should do his best to minimize harm to the environment; to let one's politicians know when you don't support a war, that they cannot say they speak for you; and so on. Being a good citizen minimizing my harmful impact on others.

So I'm confused again. Is requiring login to download a game DRM or not DRM?

Two things.
1) What is DRM for you may not be DRM for others. So buying the very same product may count as "Supporting DRM" for you, while not for the one who buys it. So if someone doesn't see Steam as DRM, buying Steam only games doesn't harm you (according to him), while it does harm you according to you. Same can be said about console games.

2) There's a phrase that says "The road to hell is paved with good intentions". So, Exhibit A and Exhibit B (nothing to do with DRM, just wanted to link those articles).
GOG requires you to login to download. You tell me ;)

Nope. Once you download it, is it yours to do with as you please indefinitely without having to do anything involving the seller (vendor, publisher, developer...) or the Internet, it has no DRM. If you can put it on any of your other computers as you see fit, it's YOURS.

... and on a PC that's running on electricity generated by nuclear or coal-fired power plants. :P

No. It's only DRM if you are uncapable of telling apart procedures that target users and procedures that target files ot its usage.

Let's take GOG as an example. The login on GOG serves to establish your individuality ( meaning it's targetting you as an individual and not your files on GOG.COM) and grant you acess to the files you should have acess to. GOG's catalogue is a common pool or resources for all of its users, the Login serves to 'distribute' those resources accordingly.

IF the login procedure is bundled with file mananagemet sofware or similar (clients, downalodaers et all) then there's DRM at play but not by virtue of the Login but by virtue of the bundling.

DRM, if present, starts at delivery (download), the point at which you propose to start making use of your files. Login comes before that, targets you not your files, and serves to establish which files you're elegible to use in the first place.

One thing is the copy protection. The copy protection scheme is old, very old and can be a disk copy protection or copy protection found in the manual, sometimes a code wheel and sometimes a serial number.

The entire point of the disk copy protection was to ensure the floppy disk behaved like a console cartridge. The game would be launched off the disk, like a cartridge, nothing else needed. No hard drive, no installations process. No copying either.

Installed games often used the copy protection through a manual or a serial number. Note that the same serial number could be used indefinitely on as many machines as you'd please and a manual could be copied - even silly codewheels or reflective paper.

That's one thing. Copy protection is passive and often little more than annoying, not restricting. It is supposed to dissuade, but can't enforce anything really. It is often mashed together these days under the DRM umbrella and sometimes, that is very fitting, but not always. The two can intersect, but they are not the same.

DRM is the bright idea that now godammit it's the 2000s and we are going to enforce our licence through various means. Not dissuade or persuade or make it annoying to circumvent the licence, but to actively *enforce* it. Directly.

That is D R M. You know when you feel it jammed unlubricated ... ahh you know where.

personally I just zip the gamefolder. If you can do that and it still works on a different computer, then it is pretty DRM free in my books.

Steam delivers games in a ready to play state. You're good to go on Transistor.
