It's a city builder in space. Basically, you juggle a bunch of different resources to keep your colonists alive and build a prosperous base. From looking at The Game List there seem to be a few games like this but I haven't played them so I can't give a comparison. It has a few different planets with different atmospheres, affecting your rate of electricity production and what disasters can occur and it has a some challenge scenarios for variety too. My main complaints would be that the lack of direct control over the behaviour of people and robots can be extremely frustrating at times as they're not super bright and that once you have stabilised, it becomes quite easy to keep everything going. Overall, I agree with Ross's rating. I had fun with it.
About as far from GaaS as you can get. It's a free download for the complete singleplayer game and appears to even be open source. Flare itself seems to be a custom engine for making ARPGs and so to show off the engine the developer(s?) have made a very by the numbers hack-and-slash experience. Story entirely consists of a few lines at the beginning and end of the game. Length is decent enough at about 6 hours depending on how completionist you are. Gameplay is pretty much like Diablo and every other "Diablo clone" on the market. The enemy model variety was a little low but there was some behavior changes on harder variants to keep it from becoming to too tedious and the difficulty progression felt pretty smooth on the whole. To use the patented Accursed Farms rating system, I'd give it a hazy, maybe just edging into good. I had some fun with it and there's nothing I hated but it does feel very generic. It seems to be still getting regular updates though so it may blossom into a great game in the future.
