I never buy games new in any case. I figure the game is going to be at least as good if not better due to patches a year from now, and lots cheaper. It's like the idea of buying Windows 7 prior to at least the first Service Pack. Who in the world???
But my refusal to buy the game with the online DRM is definitely a principles question. You shouldn't have to rely on an internet connection to play a game, unless it's an online (multiplayer) game, period. It's very Big Brother of them. I'll be glad to install the game with the registration key that comes with the game, but if, for instance, I want to shut down my internet connection so I can turn off Firewall and close my virus protection to get the most out of my system, I have the right to do it. Never mind if I shouldn't have to or not. It has to do with MY RIGHTS as a consumer.
So I will NOT be buying SH5 as long as the online DRM is required.
