DelusionsBeta: The fact that Civ V came 4th in the UK charts the week after Halo Reach launched and the week in F1 2010 launched says enough about the effects of DRM on sales (i.e. none.) And, frankly, the amount of negative publicity on Steamworks is insignificant compared to (for example) GfWL, which is why the GfWL is withering and Steamworks is hoovering up the developers that used GfWL.
I don't think DRM effects sales to any real degree across the board, that is kind of my point. I don't think 95% of people pay any attention to it, or enough attention to care. Ubisoft might have changed that with their terrible DRM, but for the most part it is invisible. I know my father in law plays shooters and such and he didn't even notice that Modern Warfare 2 activated online, he just installed, put the code in and played.
This is why I say only customer dissatisfaction changes DRM policy. Only when they have a bunch of paying customers upset about the DRM will they pay attention. This happened with Starforce, with SecuROM limits and GFWL, and those were all slowly dropped by most publishers. Steam is not hated by customers, and in fact loved by most of them, so it has been adopted by most publishers now.
Either way the point is that a sales boycott does nothing, it only lowers PC game sales even lower and companies don't assume it is a DRM issue. It harms PC gaming revenue without sending a message and you don't get to play the game either. Buying the games and sending a kind note to the publisher that it upsets you that you had to wait 12 hours to play for them to turn on the servers, or that you could not play on the airplane because you forgot to activate before you left, or whatever else... that stuff matters. Less sales is just less sales.
And on an open platform like the PC it's not like you can't find a way to play the game if the DRM is ever non-functional anyway.
DelusionsBeta: (Incidentally, AFAIK EA still use SecuROM, just larger activation limits)
I didn't mean to say they removed it from older titles, only that they no longer use it for new titles. They haven't in about a year or more... Mass Effect 2, Dragon Age, Bad Company 2, The Sims 3 and expansions, etc. etc... all are just a disc check when you buy retail.
