jlibster: Someone asked about a patch separate installer file. I do most of my stuff on Linux (and get Linux games when I can). I keep my "gaming/testing" Windows XP box separate, and off the Internet. The reason is simple: Its a great way to see if any applications installed on it are doing anything "naughty". I have clientside & dedicated hardware firewall box, and keep the sniffing tools on standby. The biggest reason for this on my Windows Box was everyone making software for the MS OS, Microsoft included, seemed to feel they had the right to have my MS windows machine, "ping" them without so much as a "by your leave". I discovered some applications or games "broke" when denyed Internet. EA/Bioware even installed a MS Windows Service with DA 1 which I manually disabled. I discovered some borderline funny business on DA1 the moment I installed any DLC. If the machine was on the Internet, I got "in game ads" so clearly privacy was being compromised. I removed Da1 and swore off the new EA/Bioware.
I love GOG because my tests confirmed no funny business. I want to continue feeling that confidence with everything I get from GOG so, it would be cool for separate, offline install options for ALL their content including Witcher 2. Is there any reasons not to if the game is DRM free? Most of these auto-installers just download a separate *.exe anyway.
I guess we can only blame pirates if there is no standalone patches. If this patcher is handled smart way it can be quite tricky for pirates to patch their games which is good (but I think they will find out around it anyways...)
