What players say
I love it. The music, style, idea, and mechanics. Don't buy it if: - Dont' like micromanagement - You want a relaxed experience - You want a good campaign, because the campaign is trash - You get frustrated easily, because this game knows how to frustrate you

Amazing game. Gameplay is fun, each new map in the campaign brings new experiences as you explore what it has to offer. Hero missions might be a bit shorter especially when it comes to higher difficulties. Art and overall design are what sells the game to me personaly in the first place. Would definitely recommend, but mind doing saves after missions and think carefully which technology to research.
I like this game, but it has one huge negative that frankly outweighs everything else. A lot of the maps you play in will take hours of real life time to play through. There is no option to speed up time, and there is no "save and retry" option. If you fail, you must play this map again from the beginning. For some of the end game maps, this can be ~4 hours. If you fail and want to try again, that's another ~4. I...
