pedrovay2003: I know I'm jumping into this conversation late, but yes, this is exactly right. I've copied/pasted DRM-free Steam games to an external hard drive, literally built two PCs from the ground up without EVER allowing them to be connected to even a local network, installed Windows, and immediately copied/pasted the backed up games to the new machine without ever putting Steam on there with it. The most I've had to do other than just start the games is to manually install required stuff like DirectX, a setup file of which is always included with any games that need it; I've never had to touch the Internet or the registry.
The same can be said of the games I posted about in my other thread, detailing how to play actual Steam games offline forever. All you need to do is copy your backed up, Offline Mode-enabled Steam folder from one PC to another, and even non-DRM-free Steam games can be played on a brand-new machine without going online or installing anything extra.
ErfInverse: Aaaaaahahahaha! Yeah, just keep believing this.. until the offline timeout runs out. It might be a month or so, a sufficiently long period of time like that to keep you falsely content and believing that the game will work forever.. until it doesn't.
The only way to keep Steam games working forever without going online is illegal. If I'm wrong on this, great, that would actually be a good thing. Maybe it works for
some games, but I doubt it so strongly that I'm going to discount that possibility entirely.
Steam's Offline Mode is indefinite. It did run out once upon a time, but Valve confirmed that it wasn't supposed to work that way, and it was patched a long time ago. And even if it did run out, you can do a lot of things with Steam by simply turning the system clock back, so it wouldn't matter regardless. For example, the next time a free weekend is happening on Steam, download the game and let the weekend end. Then, put Steam into Offline Mode and turn your system clock back a few days and see what happens to the game. Steam is incredibly easy to manipulate with minimal effort and no illegal measures.
I'm all for GOG versions of games over Steam versions, but if a Steam game doesn't have CEG, then you won't have to worry about not being able to play it in the future. On that note, I'm also curious about The Witcher 3, as mentioned above. Does anyone have the Steam version? If so, can it be run without Steam, unlike the first two games?
