Pre-release game had barely any marketing presence. I would not even hear of this game, if someone haven't added link to youtube clip of guy playing early beta late year, on some foreign forum I regulary visit. In fact, even these forums where ghastly empty up until the release.
Good: cheaper development cost, due to little or no money spend on marketing. Also explains 20$ sell price.
Bad: a lot of people will never even know this game exist.
Really Good: these forums are now busting with life, which means that word of mouth is doing its own marketing
