I'm glad to see your optimism although not share it. Time will show who is right or wrong. My point is that game story hasn't even progressed to the middle in two years. I'm agree with you that game has an unique style and i want to believe like you that project will live but little content so far doesn't sound reassuringYou're almost certainly wrong, games of this level of quality do not come from places without the love necessary to finish them. Short of WWIII, this game will be finished.
Games of this quality are also not completed quickly. It's only been like 2 years, of course the content is kinda sparse (and honestly there's a lot of content in a general objective sense anyway)
