Star Citizen is poop. Do not buy it. Get a refund if you already did.
Their community is full of deluded cultists high on their slice of the pyramid scheme arguing that a barely functional tech demo being shoved half built out the door in an effort to satisfy SC's kickstarter requirements (the date for which having come and gone) is somehow remotely passable as a game.
CIG has done nothing to earn consumer confidence. You should not give them your money on the basis of their promises. The rate of development, casual assertions of scope and the engineering debt incurred by their cash generating toys should all serve as a cautionary tale to even the most forgiving of observable red flags.
Wait until it's gold and on a store shelf. Do not buy Star Citizen now.
