They will never not use steam, there is no reason not to, not enough people dont buy the game because of steam and even just buy it on another system. There's no reason for them to discontinue using it.
The idea I was working toward was not "discontinuing it." Rather accessorizing it with other forms of distribution/validation/activation.
At this stage, the economics of it may in fact equate with "no good reason to discontinue" using Steam.
However, having a look at the proportions of respondents at this stage
Will buy no matter what ~56%
Would prefer non-Steam option, but probably still will buy ~20.5%
Will not buy if Steam required ~23.4%
. . . I would think that the risk of losing one-quarter to a half of their prospective customers from the fan community could be a good enough reason to entertain the idea of Steam non-exclusive distribution, couldn't it?
Since none of us know the actual numbers involved here, profit margins, profit sharing deals with Steam for exclusive vs non-exlucsive, etc., I admit I'm speculating (not to mention that patterns of response to a poll on here may differ quite a bit from the Steam customer base). However, the fact remains: at this stage, somewhere between 1/4 and 1/2 of the repondents to this poll say they won't buy it if it requires Steam. Seems like Bethesda should be taking an interest in what risks those patterns of response might hint at for the Skyrim release.
