The point I now made several times is that it's one of the two major projects that turned kickstarter into a popular platform. It was extremely successful at the time it was released and while projects have since outranked SC in most spend on Kickstarter, it's still one of the most successful crowdfunding campaigns of all time by any financial measure.

As for "not released", they've released a lot more than other projects have. Colossal failures such as Everquest Next have absolutely nothing to show for it - if SC stops development tomorrow (which is unlikely), they have in fact released an early stage game and a ton of near-game content.
