DO NOT BUY! Sauropod studios are run by a very small group of inexperienced, unapologetic jerks. If you bought in to this game through kickstarter or early access, they will treat you like crap on the forums.
The only thing Castle Story had going for it was the amazing work the Community Manager: Box, was doing. Box would try to give information to you straight, without breaking any of the company rules, which was very difficult to do. Box would always try to break information down to the community and calm people down who were angry about any of the situations. In the end, the company would give Box misleading information and then blame him for giving out any information to the community.
One of the primary developers for Castle Story is a dev named Thierry. Thierry has a tendency to berate the community for asking questions. On multiple occasions I've read post by him calling out individuals and virtually yelling at them, or the community in general and blaming them for being impatient. The game has been in development for years now, and there has literally been no visual improvement in over a year.
Originally there were weekly updates on what was going on, with an occasional skipping of a week or two. Now there are monthly updates on what is going on. I take that back. There are monthly video blogs about things nobody cares about. These "monthly" video blogs have only made it up to the 3rd blog before they seem to have stopped posting them. It has been six weeks since the last video blog, which is probably a good thing, because they're useless information anyway.
TL;DR, STAY AWAY FROM THIS GAME. The devs will treat you like crap, and blame the community for asking too many questions, the game has been stagnant for over a year. The forums have started seeing posts deleted, and users are getting banned for giving out useful information, and asking real questions respectfully.
