Context.
- On December 27th 2012 the pledge fund stood at £982,000 against a target of £1.2million by January 5th. A stretch goal for a native Mac version of ED was announced on the same day, if the fund reached £1.4million before the end of the campaign.
- On January 3rd 2013 the campaign reached its original target of £1.2million and ED was funded.
- On January 4th 2013 the campaign reached £1,443,634 and the Mac version was officially confirmed.
- On January 5th 2013 the campaign came to an end with a total pledged sum of £1,578,316.
There was a surge of pledges between the announcement of the Mac stretch goal and the campaign crossing the line, alongside a bunch of anecdotal quotes from Mac users announcing that they had pledged. It is not possible to determine whether the campaign would have succeeded without the Mac users' direct contributions or the attention they and the gaming media brought to the project, but they were not insignificant.
It is most unlikely that
ED would exist in its current form had the Kickstarter campaign not been successful. There's a possibility it wouldn't exist at all, although only DB/FD will ever really know what alternative strategies were on the table had the KS failed.
You're right in that the money spend on the design and development of
ED over the past six years dwarfs the original KS campaign pot. But the Kickstarter
is what got the ball rolling, and Mac users were definitely a contributor to that.
On a personal note, when the KS was funded I was looking for new hardware to replace my ageing PC both for general use and as a machine on which to play
ED. I came this >< close to dropping a small fortune on one of the then new "dustbin" Mac Pros. Given the ultimate fate of both that platform and the OSX version of
ED, I seem to have dodged more bullets than Neo when I eventually went with a new PC instead.
So I'm no hardcore Mac advocate by any means. Just pointing out that Mac users played a significant role in the Kickstarter, which in turn greenlit
ED. Some will also have been instrumental in helping to steer the early development of the game via the Backers' Forum and/or the DDF. IMO they have a right to feel a little miffed at how things turned out. The only unanswerable question is whether to point an angry digit in the direction of Cupertino or of Cambridge, or to cross one's arms and do one of each.
