I like the consistency, the art, and the fact that is is turn-based. I am an old man (51), been playing mostly RTS games for most of my life. I am not big on fast-paced FPS stuff because I can never manage the controls (neither keyboard NOR controllers), most games do NOT have auto-targeting so I get frustrated and give up after 10 minutes tops. So, a game like Gal Civ (and others like Total Annihilation and Supreme Commander) work for me because I can take my time, make decisions, and let the units do their thing... either in real time or turn-based. Also, in Galactic Civilizations, I can save the game whenever I want (in fact, it autosaves), go away, come back, and continue the muscle-memory, click-click, end turn, analyze, click-click, end turn... basically a zen-like meditation session with minimal worries about speed, aim, and the trajectory of my pointless life. I can be "in the moment", immerse myself in the gameplay, and avoid episodes of depression for HOURS at a time 😅👍🏾 People game for various reasons. This game hits the spot for me.
When this game first came out, it was barren, dry, and shallow. I personally waited 5 to 7 years before really getting into it. After getting all of the DLC and installing a few mods, I can say this is one of the best 4x Space Strategy games ever made, but it was a long road getting here. The game has plenty of depth now with the Intrigue, Crusade, and Retribution DLCs installed. The campaigns are mediocre - the sandbox mode is where the game truly shines. And this is important: the game starts up quickly, loads games quickly and smoothly, has never crashed a single time, and runs like silk even into the late game, unlike Stellaris and many other 4x Space Strategy games which take forever to load, crash often in the late game, and slow down to a crawl even on a high-end PC. Galactic Civilizations had its flaws, but for those who enjoy a smooth and clean experience it has become the standard.
I like the game but it is still bugged even after all these years. You should be able to decommission star bases and then get your administrator back. I closed down 20 of my 41-star bases and it still show on the galaxy screen that I have 41 bases rather then the 21 I should now have. Apart from the bugs this game is a very addictive, “1 more move and I will quit game but I never do”!!
