This highlights the worst part of Steam Greenlight. The developer posted a ton of ideas, some good-looking screenshots, and pitched a solid concept.
Before I even get to the review, I'd like to note that THE DEVELOPER HAS ABANDONED THE GAME. He took the "Early Access" money, cranked out an Alpha-at-best version of the game and left. He got another developer to theoretically try to finish the game, but the hopes of that actually happening are looking pretty dim.
So as for the game itself. You build a town to attract heroes to explore and clear dungeons. Sounds good. The execution is NOT. It's a buggy mess, with villagers having AI and path-finding so bad that they often get stuck and starve. You control which heroes arrive, can't tell them what to do, and can't even sell them items. The crafting system is tedious and the building system feels like it's constantly fighting against you.
It's a buggy, barely-playable mess with no endgame, few sounds, and almost no animations. Avoid like the plague.
