I am sorry to let you know but its will take a long time a lot then what you think if someone will decide to release those files .
if so may will be released bugged files or incomplete, the community go like that when game die and his activity gone well then the files will be shared when no hope to the game because right now the peoples holding the files will take a high price for them special does days , and no one know actually if they windows or Linux , me too , don't trust anybody and wait its the tip I can give you , you don't want to waste any money right now.
so before you run to buy , be sure they are real , however I wont suggest to do that action many peoples here are dropped in scammers
