the game is "technically" free up untill v1.0, you just need to wait to unlock it
About the pirate sites: i am really interested in this game, for a year I've been reading all the suggestions, all the threads and a lot of reviews,i know basically everything there is to know
and in my quest to know everything i stumbled upon sites that offer not just this game but many others
Of course something like this shouldn't be posted publicly for any random person to see
