I don't understand how Star Citizen works either and I backed it. Occasionally they send me emails which have 30 minute videos showing models of space ships, Status updates on the alpha, more videos of guys running around hangers, fan podcasts, in-universe fan fiction, etc. Occasionally I'll log in and make sure my virtual ship is still there and see what random stuff they've added. I backed at the $35 level so I only have a small scout ship. As they've raised more money I now have a Class II Space Suit with Test Pilot Colors, a Fishtank Mark 1 with Midas Fish for my virtual hanger, a virtual UFE hand towel which hangs somewhere in my virtual hanger, and other strange random virtual items. I figure eventually I'll hear that the game has been out for a week and finally download it.
