Although such a thing no doubt exists, I've never seen "Internet connection" listed in the advertised requirements of any game I
would be interested in buying.
And as for DRM stuff.
Yes, I do
now have several (disk versions) games that require using an "activation code" before being allowed to play.
But I only need to use the code on installation.
I don't have to log-in to a particular site every time I just want to play further - as I do with Steam
Unfortunately, as we are all aware, none of the DRM stuff brought out to date appears to be preventing piracy. But it certainly can upset genuine customers like me !!
However, I've no wish to start yet another thread on THAT subject so I'll shut up now !!!!
