I have to agree with Karlston and sygnus21's points. I am having a hard time with the "always connected" scheme, mostly because I have no control over it. For example, I am not a play it and throw it away type of gamer, I tend to revisit them years later (I have an old, slow machine set up for DOS just so I can revisit the really old ones in their original, pure, crappy style
.) So let's say 10 years down the road I want to break out my old copy of Settlers 7 and give it a go, who's to say the servers will still be active or the company even still in business?
Granted, it is possible they would release a patch to remove the DRM after they decided to no longer support it (it has been done) but I think I need more guarantees before I'll buy into this system.
