I was one of the original Kickstarter funders.
I threw my money into the pot because I got so much fun and game play out of the original Elite. Basically I thought David Braben and his team had already earned it. Am I disappointed that there's no single player offline? Yes, I am. My home internet connection has a long ping time (it's via satellite) so multiplayer combat was never going to work for me. It may be, for that reason, the game won't work at all - FOR ME. But I'm not making a fuss.
Basically if you back a kickstarter you're taking a risk. This kickstarter has enabled an amazing game to be built, and lots of people will get a huge amount of fun out of it; as far as I'm concerned, my money's well spent.
