Star Citizen has the honor of being the biggest crowd funded game ever and they are getting more money all the time, but with what had been playable so far you might question where the money went to as there was not much too actually play. Well in the past few days they have released a massive update for the backers which add a lot more meat to the bones of the game. Here is a link to what has been included.
My own thoughts: I downloaded the update but unfortunately seem to have had quite a few issues, with it crashing and unable to access servers or being stuck at the load screen hopefully it will be resolved soon and I know it is an alpha but it is hard to test a game if the game will not load.
