I'm not a backer, but your sentiment seems right. It always seemed like a game that wanted to be "the best space sim", and that is going to take a while. All the demos have looked incredible, a the features are extremely ambitious, but cool.
I think that all backers should just feel lucky the project hasn't burned through all their cash and shut down yet.
I agree with this too. It's all about your general outlook on things. Plenty Kickstarters have failed and vanished. Will this project do the same? I don't know, but I don't think so. When I contributed, I parted with the amount of money I was comfortable never seeing again.
