StingingVelvet: Old post but I wanted to correct you... not sure if it is a Euro thing, but all the games I listed CERTAINLY had online activation in the US and all of them had it patched out. If Euro is different good for you, but I only used examples I was completely sure of, and there they are. There are many others as well.
No I was talking about the US version... I ordered the US version to STALKER especially because it was copy protection/DRM free unlike the Euro one which had a CD-check
But are you sure that the version you are talking about the
STEAM version IRC the Steam version of STALKER has an extra online activation DRM added on top of Steam... Personally I was talking about the retail version.
In case you were talking about retail version, did you test it ? (install and play the game while being offline on an OS on which it was never installed)
About the games you mention:
Stalker (US retail) never had any online activation : I am sure, own it.
X 3 (US retail) never had any online activation : I am sure, own it too.
Anno 1404 (US retail) : this one I don't own it and I haven't tested it personally but never heard anybody mentioning that the DRM was removed.
Farcry 2 (US retail): should still had its online activation, talked about it with a friend some weeks ago and with latest patch it still had it's online activation, so unless a patch removing it has been released very recently (than 2-3 weeks) it should still had it... unless of course it's my friend who screw up this one.,
