StingingVelvet: The Witcher 2 already proved DRM matters little to the average consumer. They heavily promoted and discussed the DRM version on GOG and yet the Steam version outsold it like 10 to 1, or more.
No one gives a shit.
Sorry, but this is absolutely not true.
"For the first six months following launch CD Projekt shifted 35,000 copies of the game digitally through GOG.com, which it owns. GOG.com sold the second most units across all platforms.
Top was, of course, Steam. More than 195,000 units were sold through Valve's digital platform. All other digital distribution outlets combined sold approximately ten thousand units. "
http://www.eurogamer.net/articles/2011-11-10-cd-projekt-witcher-2-gog-com-sales-vindicate-drm-free-decision So it's only 5,5 times more on Steam than here. And that's when Steam is so much bigger than GOG (in terms of sales per day, daily users logged in, etc.).
If Witcher 2 proved something, is that there are many people (about 20%) who buy their games in digital distribution, who care about the DRMfree.
You should also be aware of the fact that according to that data, only 1/5 of the people who bought The Witcher 2 chose Steam. 800k chose retail over Steam, which was also DRM-free right after the release.
So please don't make simple assumptions, The Witcher 2 showed that DRM-fee crowd is important part of the market. Just important, as "No Steam - no buy".
But of course, most important part is "give me a good game".
