This was mentioned in the "upcoming indie games to watch" thread but hasn't gotten much attention. Given GWJ's love of Dwarf Fortress I was surprised and thought maybe it was just overlooked and due its own thread. As said in the title, Gnomoria is very much influenced by Dwarf Fortress, although currently it's a bit shallower of a rabbit hole. I've sunk a lot of time into this over the last few days and have been really enjoying it. It's just about the perfect game for anyone who wanted the Dwarf Fortress experience but couldn't get past the interface.
Currently Gnomoria is in alpha. There's a demo that you can play for 6 game days, which lets you get surprisingly far, and you can purchase the alpha at 20% off, $7.99 rather than $9.99. The full version will let you continue your game from the demo. The dev is listening to suggestions so it's also a great time to get in and possibly shape the game.
