Happy to see they put some of the extra money to adding Mac support. I wish I saw that news before the window closed, since I ignored the project on first hearing about it because they were going windows-only.
Now I see that the Wasteland 2 project also says it is Windows only, but "Maybe" they will add mac compatibility if they get 1.5mil.
This suggests that Kickstarter needs a new feature: Pledges that are conditional not just on the project succeeding, but pledges that are conditional on the project exceeding successive tiers of ambition.
