Gnomoria is a detailed base-building game in which one pits a tribe of gnomes against evils from the depths of their mines and evils from other, invisible, villages. Gnomes are able to mine a variety of resources, process them, and manufacture everything from furniture to armor. They have to sleep, eat, and drink, and they can even become powerful zombies after death, returning later to slaughter any former friends that are caught unaware.
It's a fun game with plenty of opportunity for strategy and mayhem.
But, here's the thing: this game has been in Early Access forever, updates are slow, bug fixes are slow, and the game is using outdated technology (XNA, which was discontinued by Microsoft in early 2013) that doesn't even support some relatively common desktop features like 1440p resolution.
A year ago, I would have said Gnomoria is a hugely promising game and worth buying for double the price, but that's about when the developer slowed down. A lot. The game I was playing a year ago is very nearly the same game I could play today, were I to click the Play button again.
My advice: hit that "Follow" button on the store page, and if Gnomoria ever releases, give it another look. I certainly will.
