First of all, this game is still in beta so purchase at your own risk.
tl;dr: Great game for those who love complex strategy and/or creativity and don't mind a few technical issues. However still lacking features and still prone to crashes and bugs.
The game is fun and nostalgic for those who played older GalCivs but it's still far from being complete. The game itself is quite complex, mostly ranging from managing your economy and research whilst also building up your armada to defend your civilization. Other than that, you can build your own ships tailored to the situation and your own creativity, you can build anything from the smallest scouts to intimidatingly huge battleships. You can also build specialized ships like fragile but deadly snipers or even a craft specialized with sensors to see the enemy coming from sectors away. You can even win in your own way, conquering through military (let's be honest, the most fun and easy method), cultural or technological might. These elements combined with future content seems rather promising for a strategy game, especially as the developpers seem keen to both add content to the game and fix current issues.
However, let us remember that it's a beta and is therefore prone to many, many issues, amongst the most pressing:
-Many, many bugs, rarely play over 30mins without any technical problems (especially true late game)
-You lose your save data (or, to be precise, the ability to use them as they are no longer compatible) every few patches
-Many features have yet to be implemented
-The AI can be somewhat... crude and annoying
Despite this, I will still recommend this game as it is still fun and keeps me in the "one more turn" mentality for hours on end.
